Facebook on Friday moved ahead with proposed changes to its privacy policies to clarify that users’ posts on the site can be used in advertisements, but that users have controls to limit their appearance. In August, Facebook proposed revisions to its Statement of Rights and Responsibilities, in which it said that it can use the names, profile pictures and other data of its members to deliver ads. The proposed changes drew sharp criticism from some users, privacy groups and the U.S. Federal Trade Commission, which launched an examination into whether the amendments violated a 2011 law. The updated policies largely stand and will go into effect immediately, Facebook said on Friday. “Your feedback was clear — we can do better — and it led to a number of clarifying edits,” said Erin Egan, Facebook’s chief privacy officer. Nothing about the update, however, has changed Facebook’s advertising policies or practices, she said in a blog post.
