800K FACEBOOK USERS MAY HAVE HAD UNBLOCKING BUG

More than 800,000 Facebook users may have been affected by a bug that unblocked people they previously had blocked, the company said Monday. While the person unblocked could not see content users shared with their friends, they could have seen content posted to a wider audience. The bug, active between May 29 and June 5, has been fixed, Facebook said.
