At the direction of 49 state attorneys general, Facebook has adopted even more provisions to restrict interactions between adults and teenagers. Along the changes are automatic reviews of any age-changes made to underage user profiles, and the deletion of links to "pornographic materials." Even though most young people approached for sex by adults on social networks are already onto their date-of-birth deception, Chief Privacy Officer Chris Kelly's pledge to make Facebook safer for The Children makes for a good press op. Will the new rules make any difference, and how are they going to be implemented? We've asked Facebook how many engineers report to Kelly, but until they get back to us, it's safe to guess exactly none.
