EPIC sent a letter requesting that the Federal Trade Commission determine whether changes Facebook has made to the profiles of its users are consistent with the terms of a settlement reached between Facebook and the FTC. EPIC's letter states that "with Timeline, Facebook has once again taken control over the user's data from the user and has now made information that was essentially archived and inaccessible widely available without the consent of the user." The settlement requires Facebook to give users clear and prominent notice and obtain users' express consent before changing their privacy settings. EPIC sent a similar letter to the FTC about Timeline and the secret tracking of users in September 2011. For more information, see EPIC: Facebook Privacy, and EPIC: FTC Facebook Settlement.
