As dating apps try to pivot to virtual events, some users are trying to get people to violate social distancing rules

  • Dating apps like Tinder, Bumble, and Hinge have reported increased use amid the coronavirus pandemic, while touting virtual dating alternatives for users instead of meeting up in person.
  • Swaths of users are still encouraging matches to break quarantine to have sex and go on dates, despite social distancing guidelines and fines to comply with them.
  • An illustrator on Instagram has been collecting screenshots of these situations, and told Business Insider that users will brand themselves as "badasses," dispute the effectiveness of isolating, and lash out in anger and hurl abusive language when they're rejected.
  • Spokespeople for Grindr, Tinder and Bumble told Business Insider they've informed users to adhere to social-distancing guidelines, but did not respond to inquiries about actions they're taking against users in places where violating lockdown orders can be against the law.
  • Visit Business Insider's homepage for more stories.

As millions remain confined to their homes to prevent the spread of coronavirus, the desire for human contact and connection has risen dramatically and led some to search for ways to break those social distancing rules.

Popular dating apps — including Tinder, Bumble, and Hinge — have reported significant increases during the outbreak of swiping activity, matches between users, and messages exchanged. It's also led to the introduction of a breed of users who are interested in shirking lockdown orders, and are encouraging their matches to join them in doing the same.

Dating app users have shared stories across social media, and recently with Mashable, about messages they've received from matches who ask them to come over or want to hook up. Artist Samantha Rothenberg, who uses the handle @violetclair on Instagram, has been collecting these screenshots from followers, and told Business Insider she's received close to a thousand of such stories.

"Because of how common it is, I can honestly say that anyone who is on a dating app right now has dealt with this," Rothenberg told Business Insider. "People are horny, and a lot of people are putting that ahead of the risk and the danger."

For dating platforms whose end goal is inherently to bring its millions of users together in real life, the coronavirus outbreak has put them in a curious predicament. Dating apps are forced to balance a desire to keep people on their platform for the sake of business, with a moral responsibility to discourage users to engage in behavior with potential life-or-death implications.

Since the start of the outbreak, apps have rolled out in-app virtual dating options and touted ways users can go on virtual dates. However, the prevalence of users who are trying to meet up in person, as documented by Rothenberg and screenshots across social media, raise questions about whether these dating platforms are doing enough to stymie such behavior in the time of coronavirus.

Rothenberg has long collected screenshots of users' horror stories from dating app interactions, which she often will depict in illustrations she posts to her Instagram account. But ever since the pandemic led states to instill lockdown orders starting in March, nearly all of the screenshots she's received have had to do with coronavirus.

These lockdown-violating users fall into a few general categories, according to Rothenberg. There's the users who try to paint themselves as "badasses" for breaking the rules, though Rothenberg says they're more like "a--holes." There are the matches who propose meeting up and, after getting rejected, reverse course to say they're were joking or "testing" you, she says. You'll also encounter the anti-quarantine user, whose reasoning is based on claims about herd immunity and the ineffectiveness of social distancing measures.

The last group is made up of users who react to "no" with anger and verbal abuse, Rothenberg told Business Insider. Women told Mashable recently about encounters with men on dating apps who badgered and harassed them after they turned down in-person meetings, going to the point of gaslighting.

These types of users are what led Rothenberg to launch a petition on Change.org to hold dating apps responsible for enforcing social distancing guidelines during the pandemic. She's also been active about calling out dating apps in her Instagram Stories she posts with screenshots she receives.

"People are angry, they tell me, 'can you believe this, this is disgusting, this is wrong,'" Rothenberg said. "Because I have this platform, I feel I have a bit of a responsibility to put these [stories] out in the open and share, and bring some light into what's going on out there to people who may not know."

In late March, platforms sent out various messages and alerts to their users that Rothenberg documented on Instagram. A message to Bumble users from CEO Whitney Wolfe Herd said: "Please don't meet your Bumble matches IRL for now." Hinge users were told to "stay safe and keep connected."

Tinder, arguably the most well-know dating app, also discouraged users to meet up in a platform-wide message sent March 26.

"We know there's a lot to stay to each other as we all do our best to stay healthy and prevent the spread of the coronavirus," the message from Tinder said. "We hope to be a place for connecting during this challenging time, but it's important to stress that now is not the time to meet IRL with your match."

Dating apps' responsibilities to pivot from IRL to TXT

As companies across industries adjust business to stay afloat, dating apps have transitioned to emphasize alternatives to in-person meetups. Although online dating success has long been measured by the amount of conversations that turn to real-life connections, platforms are forced to rethink their strategy as users continue turning to them en masse. A poll conducted by Hinge found that 70% of its users said they were open to going on dates on Zoom, FaceTime, and other video platforms.

Some dating brands have introduced new features amid the pandemic. Hinge launched "Date from Home" in April, where users can indicate to a match they're ready to move their conversation off-app. Plenty of Fish started rolling out a livestreaming feature in March to users in the U.S. to allow matches to go on short virtual dates. Tinder, relatively late to the game, announced this week it was launching a video chat feature by the end of June.

A spokesperson for Match Group — the parent company on Tinder, Hinge, Plenty of Fish, and other dating platforms — told Business Insider that it made updates to its products "to help users better navigate stay-from-home policies and date digitally via phone or video."

Other apps that already enabled video chat and voice call, like The League and Bumble, are pushing these features to their users more than ever. 

But while users on these dating apps are swiping and messaging at new highs, the transition to virtual-only hasn't been as seamless for those on Grindr, the most popular dating app for gay men. Steve, a 26-year-old living in Washington, D.C., told Business Insider that activity on Grindr is "completely dead." He said he doesn't check the app nearly as often any more, but messages he does get on the app are largely from people who say they want to meet up despite the quarantine.

Grindr, like other apps, has attempted to pivot to virtual dating: The platform recently introduced Circles, where groups of up to 20 users can join chats centered around certain topics and interests. However, Steve said he's seen these groups largely dissolve into "all d--k pics."

"I dont think Grindr has the ability to rebrand itself honestly at this point for something other than hookups," Steve said. "They tried to take the opportunity to rebrand itself as something else, and it just right away became sexual."

A Grindr spokesperson told Business Insider it had sent in-app notifications to all users asking them to "refrain from in-person meetings right now."Nonetheless, an app-wide message sent to users — and shared by users on Twitter — made no mention of asking users to social distance. 

For users across these dating apps who encourage the violating of social distancing guidelines, it's unclear how much responsibility platforms have to keep their users' indoors. In some states under lockdown, authorities have doled out fines and even arrested residents found failing to follow at-home guidelines.

Grindr, Bumble and Match Group — the parent company of Tinder, Hinge, Plenty of Fish and others — told Business Insider in statements they have encouraged users to adhere to coronavirus guidelines from the World Health Organization and the Center for Disease Control.

None of the companies responded to Business Insider's requests for comment about whether asking to violate social-distancing guidelines on the platforms is a breach of policy or would garner any ban or suspension on a user.

N{alpha}-Acetylation of the virulence factor EsxA is required for mycobacterial cytosolic translocation and virulence [Molecular Bases of Disease]

The Mycobacterium tuberculosis virulence factor EsxA and its chaperone EsxB are secreted as a heterodimer (EsxA:B) and are crucial for mycobacterial escape from phagosomes and cytosolic translocation. Current findings support the idea that for EsxA to interact with host membranes, EsxA must dissociate from EsxB at low pH. However, the molecular mechanism by which the EsxA:B heterodimer separates is not clear. In the present study, using liposome-leakage and cytotoxicity assays, LC-MS/MS–based proteomics, and CCF-4 FRET analysis, we obtained evidence that the Nα-acetylation of the Thr-2 residue on EsxA, a post-translational modification that is present in mycobacteria but absent in Escherichia coli, is required for the EsxA:B separation. Substitutions at Thr-2 that precluded Nα-acetylation inhibited the heterodimer separation and hence prevented EsxA from interacting with the host membrane, resulting in attenuated mycobacterial cytosolic translocation and virulence. Molecular dynamics simulations revealed that at low pH, the Nα-acetylated Thr-2 makes direct and frequent “bind-and-release” contacts with EsxB, which generates a force that pulls EsxB away from EsxA. In summary, our findings provide evidence that the Nα-acetylation at Thr-2 of EsxA facilitates dissociation of the EsxA:B heterodimer required for EsxA membrane permeabilization and mycobacterial cytosolic translocation and virulence.

Structure-based discovery of a small-molecule inhibitor of methicillin-resistant Staphylococcus aureus virulence [Molecular Biophysics]

The rapid emergence and dissemination of methicillin-resistant Staphylococcus aureus (MRSA) strains poses a major threat to public health. MRSA possesses an arsenal of secreted host-damaging virulence factors that mediate pathogenicity and blunt immune defenses. Panton–Valentine leukocidin (PVL) and α-toxin are exotoxins that create lytic pores in the host cell membrane. They are recognized as being important for the development of invasive MRSA infections and are thus potential targets for antivirulence therapies. Here, we report the high-resolution X-ray crystal structures of both PVL and α-toxin in their soluble, monomeric, and oligomeric membrane-inserted pore states in complex with n-tetradecylphosphocholine (C14PC). The structures revealed two evolutionarily conserved phosphatidylcholine-binding mechanisms and their roles in modulating host cell attachment, oligomer assembly, and membrane perforation. Moreover, we demonstrate that the soluble C14PC compound protects primary human immune cells in vitro against cytolysis by PVL and α-toxin and hence may serve as the basis for the development of an antivirulence agent for managing MRSA infections.

Reimagining Trade Rules to Address Climate Change in a Post-Pandemic World

Webinar Research Event

5 May 2020 - 2:00pm to 3:00pm

Event participants

James Bacchus, Distinguished University Professor of Global Affairs and Director of the Center for Global Economic and Environmental Opportunity at the University of Central Florida; Member and Chair, WTO Appellate Body, 1995 - 2003
Chair: Creon Butler, Director, Global Economy and Finance Programme, Chatham House

This event is part of the Chatham House Global Trade Policy Forum and will take place virtually only.

International trade has a crucial role to play in tackling climate change. The production and transport of goods is a major contributor to green-house gas emissions, as is the delivery of certain cross-border services. At the same time, it looks inevitable that the COVID-19 pandemic will lead to a radical re-think of global supply chains as companies and governments seek to build in greater resilience while at the same time preserving as far as possible the efficiency gains and lower costs that global supply chains generate when operating normally.

Future international trade rules will have a crucial role to play in addressing both challenges; they represent both an opportunity and a risk. If designed well, they could play a very important role in re-enforcing moves towards a more sustainable use of resources, greater overall alignment of economies with the Paris Agreement, and greater economic resilience. But they could also, if poorly designed and implemented, or overly influenced by strategic political considerations, have significant unintended and negative implications. These include: reduced economic efficiency, increased poverty, unnecessary economic decoupling and reduced consensus on the broader mitigation and adaptation measures required to meet the challenge of climate change.

Against this background, a number of key questions arise: In what areas, if any, do we need to modify or adapt key principles underlying the system of global trade rules in order to respond to the twin challenges of responding to climate change and building greater economic resilience?  Which are the most promising/practical areas on which trade policy experts should focus now to re-launch/re-energize discussions on WTO reform, including, for example, dispute settlement? What national economic policies will be needed to complement the development of new/reformed trade disciplines in these areas? How might future political changes, such as a change in the US administration, affect the prospects for and political momentum behind such deliberations? What in any eventuality is the best way to build the required political momentum?
 
This roundtable is convened by the Global Economy and Finance Programme and the US and the Americas Programme and it is part of the Chatham House Global Trade Policy Forum. The event will take place virtually only.

Lawbreaking violates rule of law

The violence and vandalism in recent months sparked a crisis of confidence of our rule of law. The so-called justice lawbreaking or civil disobedience is never justified under the law. I urge all of you not to engage in any illegal activities.

 

The Court of Final Appeal in its judgment (FACC8-10/2017) pointed out that: (1) unlawful assemblies involving violence, even a relatively low degree, will not be condoned and may justifiably attract sentences of immediate imprisonment in the future; and (2) little weight will be given to the mitigation that the offending act was committed in the exercise of constitutional rights or acts of civil disobedience because the fact of a conviction will necessarily mean the offender has crossed the line separating the lawful exercise of his constitutional rights from unlawful activity subject to sanctions and constraints.

 

There are suggestions that deliberate lawbreaking might be considered to achieve objectives, however, this would bring a wrong concept of the rule of law. The escalated violence and vandalism in the last few months have also undermined the perception of the rule of law among the public. My colleagues and I would promote and publicise the correct concept of the rule of law to the citizens through different channels. In analysing the current situation, I hope that we all could remain reasonable and objective by keeping an open mind, being informed and considering all relevant facts before coming to a conclusion.

 

Our rule of law has been highly regarded, and such an achievement was not easy to come by. We should all join hands to cherish and safeguard our rule of law. Abiding by the law is one of the many obligations that ought to be observed by the public. Law exists in practice but it should not only be practised by lawyers, judges and governments. More importantly, the rule of law should be observed and respected by the community as a whole. The Government would continue to be strongly committed to upholding the rule of law.

Alleged rule breaches probed

(To watch the full press briefing with sign language interpretation, click here.)

 

Chief Executive Carrie Lam today said law enforcement agencies are investigating cases where police officers are suspected of breaching property rules and will give a full account to society.

 

Speaking to reporters before the Executive Council meeting this morning, Mrs Lam said nobody is above the law.

 

“The law will be applied in the same manner regardless of the status, the background, the political affiliation of that particular person.

 

“As far as I am concerned, as the Chief Executive of Hong Kong and also as an individual, no law-breaking behaviour is acceptable. But it is not for me to stand here to judge each and every case because every case or every complaint has to be investigated and analysed by the law enforcement agencies.

 

“I am sure that they will do it as diligently as possible and will give a full account to society, especially given the recent concerns.”

Scheduled premises' rules clarified

Premises can still operate other licensed businesses which are not required to be suspended if they were operating more than one licensed business before the closure, the Food & Health Bureau said today.

 

The bureau made the statement in response to media enquiries on some anti-epidemic measures which were relaxed from today.

 

The statement noted that in accordance with the Prevention & Control of Disease (Requirements & Directions) (Business & Premises) Regulation, the Secretary for Food & Health has issued directions by notices in the Gazette that certain scheduled premises, namely karaoke establishments, clubs or nightclubs, party rooms and bathhouses, should remain closed until May 21.

 

These scheduled premises may still operate other licensed businesses if the operators have implemented all measures to effectively stop or avoid operation of businesses and offering services which are required to be suspended.

 

For example, premises originally operated as karaoke establishments and catering businesses can continue their catering business in accordance with the relevant directions if all karaoke operation and services are suspended.

 

The directions state that facilities, installations and equipment for karaoke activities are closed or properly sealed off and notices are posted in prominent locations at the entrances clearly indicating that only catering services but no karaoke services are provided in the premises.

 

Other scheduled premises operating more than one licensed business can adopt similar measures to operate other licensed businesses which are not required to be suspended, the bureau added.

Blistering1 Modulates Penicillium expansum Virulence Via Vesicle-mediated Protein Secretion [Research]

The blue mold fungus, Penicillium expansum, is a postharvest apple pathogen that contributes to food waste by rotting fruit and by producing harmful mycotoxins (e.g. patulin). To identify genes controlling pathogen virulence, a random T-DNA insertional library was created from wild-type P. expansum strain R19. One transformant, T625, had reduced virulence in apples, blistered mycelial hyphae, and a T-DNA insertion that abolished transcription of the single copy locus in which it was inserted. The gene, Blistering1, encodes a protein with a DnaJ domain, but otherwise has little homology outside the Aspergillaceae, a family of fungi known for producing antibiotics, mycotoxins, and cheese. Because protein secretion is critical for these processes and for host infection, mass spectrometry was used to monitor proteins secreted into liquid media during fungal growth. T625 failed to secrete a set of enzymes that degrade plant cell walls, along with ones that synthesize the three final biosynthetic steps of patulin. Consequently, the culture broth of T625 had significantly reduced capacity to degrade apple tissue and contained 30 times less patulin. Quantitative mass spectrometry of 3,282 mycelial proteins revealed that T625 had altered cellular networks controlling protein processing in the endoplasmic reticulum, protein export, vesicle-mediated transport, and endocytosis. T625 also had reduced proteins controlling mRNA surveillance and RNA processing. Transmission electron microscopy of hyphal cross sections confirmed that T625 formed abnormally enlarged endosomes or vacuoles. These data reveal that Blistering1 affects internal and external protein processing involving vesicle-mediated transport in a family of fungi with medical, commercial, and agricultural importance.

The rule of law and maritime security: understanding lawfare in the South China Sea

4 September 2019 , Volume 95, Number 5

Douglas Guilfoyle

Does the rule of law matter to maritime security? One way into the question is to examine whether states show a discursive commitment that maritime security practices must comply with international law. International law thus provides tools for argument for or against the validity of certain practices. The proposition is thus not only that international law matters to maritime security, but legal argument does too. In this article, these claims will be explored in relation to the South China Sea dispute. The dispute involves Chinese claims to enjoy special rights within the ‘nine-dash line’ on official maps which appears to lay claim to much of the South China Sea. Within this area sovereignty remains disputed over numerous islands and other maritime features. Many of the claimant states have engaged in island-building activities, although none on the scale of China. Ideas matter in such contests, affecting perceptions of reality and of what is possible. International law provides one such set of ideas. Law may be a useful tool in consolidating gains or defeating a rival's claims. For China, law is a key domain in which it is seeking to consolidate control over the South China Sea. The article places the relevant Chinese legal arguments in the context of China's historic engagement with the law of the sea. It argues that the flaw in China's approach has been to underestimate the extent to which it impinges on other states' national interests in the maritime domain, interests they conceptualize in legal terms.

Reimagining Trade Rules to Address Climate Change in a Post-Pandemic World

Webinar Research Event

5 May 2020 - 2:00pm to 3:00pm

Event participants

James Bacchus, Distinguished University Professor of Global Affairs and Director of the Center for Global Economic and Environmental Opportunity at the University of Central Florida; Member and Chair, WTO Appellate Body, 1995 - 2003
Chair: Creon Butler, Director, Global Economy and Finance Programme, Chatham House

This event is part of the Chatham House Global Trade Policy Forum and will take place virtually only.

International trade has a crucial role to play in tackling climate change. The production and transport of goods is a major contributor to green-house gas emissions, as is the delivery of certain cross-border services. At the same time, it looks inevitable that the COVID-19 pandemic will lead to a radical re-think of global supply chains as companies and governments seek to build in greater resilience while at the same time preserving as far as possible the efficiency gains and lower costs that global supply chains generate when operating normally.

Future international trade rules will have a crucial role to play in addressing both challenges; they represent both an opportunity and a risk. If designed well, they could play a very important role in re-enforcing moves towards a more sustainable use of resources, greater overall alignment of economies with the Paris Agreement, and greater economic resilience. But they could also, if poorly designed and implemented, or overly influenced by strategic political considerations, have significant unintended and negative implications. These include: reduced economic efficiency, increased poverty, unnecessary economic decoupling and reduced consensus on the broader mitigation and adaptation measures required to meet the challenge of climate change.

Against this background, a number of key questions arise: In what areas, if any, do we need to modify or adapt key principles underlying the system of global trade rules in order to respond to the twin challenges of responding to climate change and building greater economic resilience?  Which are the most promising/practical areas on which trade policy experts should focus now to re-launch/re-energize discussions on WTO reform, including, for example, dispute settlement? What national economic policies will be needed to complement the development of new/reformed trade disciplines in these areas? How might future political changes, such as a change in the US administration, affect the prospects for and political momentum behind such deliberations? What in any eventuality is the best way to build the required political momentum?
 
This roundtable is convened by the Global Economy and Finance Programme and the US and the Americas Programme and it is part of the Chatham House Global Trade Policy Forum. The event will take place virtually only.

We would like to take this opportunity to thank founding partner AIG and supporting partners Clifford Chance LLP, Diageo plc, and EY for their generous support of the Chatham House Global Trade Policy Forum.

Please note this event is taking place between 2pm to 3pm BST.

USCIS Fee Increase Proposed Rule Could Represent the Latest Step in Reshaping Immigration to United States

While much attention has been given to the move by U.S. Citizenship and Immigration Services to raise its application fees—including an 83 percent hike to apply for U.S. citizenship—the policy changes embedded in the proposed rule have been less scrutinized. The changes, including the elimination of most fee waivers for lower-income applicants, would likely reduce the number and shift the profile of those getting a green card or other immigration status.
