Social Media Data Scraped And Found Unprotected Online

A database of 235 million social media profiles were found unsecured by researchers with Comparitech. While data scraping is technically legal, it goes against the terms of use for the brands affected.

The Facts:
Data scraping is the act of moving information from a website into an actionable form like an Excel spreadsheet or computer file. Such a technique can be benign under certain paradigms. For example, travel comparison sites like Trivago and Kayak deploy a program that scrapes hotel and airline sites for rates which it compiles on their website. Data scraping is commonly used by marketers to paint a clearer picture of their target base and advertise to them accordingly.

However, social media data scraping and aggregating is an effective way for hackers to quickly and easily scale phishing schemes and engage in fraudulent activities. Additionally, scraped data can be sold to companies who engage in spam practices as a means of advertising. Although spam remains legal in most jurisdictions, it is condemned as a legitimate marketing strategy. Finally, data scraping is commonly used on social media sites to steal content from influencers and repost it under a fraudulent account. It is for this reason that Facebook and Instagram banned the now defunct data scraping company,

Lawsuit Challenges Clearviews Use of Scraped Social Media Images for Facial Recognition

Facial recognition technology is getting more sophisticated, more reliable, and more pervasive as the world eases its way toward becoming an all-encompassing surveillance state. That surveillance state does not even have to be built; it is increasingly ready for deployment as law enforcement agencies cut deals with private companies that have already assembled the tools and databases for use. As with cell phone tracking, that plug-and-play quality does an end-run around safeguards that, at least nominally, restrict government actors, and invites legal challenges based on civil liberties concerns.

Facebook Has Lost its Dominance Among Key Demographics and Social Media Users

There was a time not all that long ago when Facebook was considered to be the absolute pinnacle of social media in general. Because of the fact that this is the sort of thing that could potentially end up being no longer the case without widespread innovation, Facebook has worked quite hard to diversify its offerings. However, recent data suggests that in spite of the fact that this is the case, Facebook has now lost its dominance among key demographics as well as social media users in general.

According to research conducted by the EdisonResearch, two very intriguing statistics have emerged. The first is that Facebook is no longer the social media platform of choice for people between the ages of 12 and 34. This is arguably the single most important demographic out there due to the reason that these are the people that the vast majority of advertisers are going to want to target at any given point in time. Only 21% of users between 12 and 34 years of age say that Facebook is their social media brand of choice.
