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,

The 5 Most Important Stages in the Content Marketing Process

Looking to implement a content marketing plan for your business, but not sure where to begin?

Used well, content can help you maximize connection with your target audience, and become a key resource in your niche. Your content can boost brand awareness, exposure, and eventually, lead to greater business success as potential customers become aware of your brand and its expertise.

So where do you begin?

The key to content success is mapping out a full strategy from the beginning, so you know not only what you're going to create, and where you'll share it. But also, what metrics you'll be using to measure its success, and how you can track performance over time.

An effective content strategy does take time to generate results, and if you have not aligned with the right metrics, you can come off the rails quickly.

Fashion brands should engage more proactively around sustainability on social media

Rather than using aggregated statistics and sentiment analysis, the research team used a qualitative approach to drill down into all the tweets posted around the two case studies, and divided them into key topics, positions, purpose and arguments, in order to determine how users engaged in the debate around sustainability and ethics in fashion.

They found that the two main ethics and sustainability issues raised by social media users were environmental concerns, in the first case study; and labor conditions in the supply chain, in the second. Analysis revealed that only a small proportion of tweets were explicitly critical and that those that were, were actually prompting a relatively sophisticated debate that fashion brands may benefit from engaging meaningfully with.
