An anonymous reader quotes a report from Gizmodo: Facebook disclosed a new "bug" on Monday that temporarily let some users who'd been blocked on the service send messages to the people who had blocked them. The bug also let some previously-blocked users view posts that were shared "to a wider audience," such as publicly or with friends of friends, Facebook said. Facebook's privacy boss Erin Egan apologized for the error, writing in a blog that the company is reaching out to "over 800,000" users about the screw-up. The "blocking bug" was active between May 29 and June 5, for eight days, though the company now says Messenger should be acting normally. According to Egan's post: "[the bug] did not reinstate any friend connections that had been severed; 83% of people affected by the bug had only one person they had blocked temporarily unblocked; and Someone who was unblocked might have been able to contact people on Messenger who had blocked them."
