The Electronic Privacy Information Center (EPIC) has previously filed complaints against Facebook, and was largely successful in their efforts. Their current formal complaint asks the agency to begin an investigation, and comes in response to the news that Facebook manipulated the News Feeds of 689,003 users.
The the Federal Trade Commission's (FTC) 2012 settlement with Facebook followed from a Complaint filed by EPIC and a coalition of privacy and civil liberties organization in December 2009 and a Supplemental Complaint filed by EPIC in February 2010. In that matter, the FTC settled charges that Facebook “deceived consumers by telling them they could keep their information on Facebook private, and then repeatedly allowing it to be shared and made public.”
