Despite this “search clause”,” you may have been surprised to learn that in the summer of 2012, Facebook experimented for a week with nearly 700,000 Facebook users. The site manipulated its news feeds to prioritize positive or negative content and sought to determine whether emotions spread contagiously on social media. There was no age limit for the data, meaning it may have been users under the age of 18. The Cornell researchers then analyzed the data from Facebook. The resulting study, published in the Proceedings of the National Academy of Sciences, showed that emotional states can be transmitted on social media. The company`s chief executive, Sheryl Sandberg, has since apologized for the study and called it “misinformed.” Your Facebook fingerprint doesn`t necessarily disappear when you deactivate your account. In accordance with the site`s statement of rights and obligations, your videos or photos, if they have been shared by other users, will remain visible on the site after you deactivate your account and will be subject to that user`s privacy settings. This means that Facebook is paid to provide brands or businesses with your recommendation (which you indicate by liking a page). You can even determine the value of your data to Facebook using Disconnect, Inc.`s FBME app. And a report from the Center for Digital Democracy shows that marketing companies are taking note of this and developing algorithms to determine the main “influencers” of social media. The report showed that many distributors have identified young multicultural users as important influencers and have addressed this demographic by strengthening social media marketing. .
