Over 800,000 Facebook users have been affected by a bug on both Facebook and Messenger, which meant that blocked users were temporarily unblocked.
The bug was active from May 29 – June 5, Facebook revealed in a blog .
Erin Egan, Chief Privacy Officer at Facebook, explained: “While someone who was unblocked could not see content shared with friends, they could have seen things posted to a wider audience.
“For example pictures shared with friends of friends.
"We know that the ability to block someone is important — and we’d like to apologise and explain what happened.”
Facebook explained that the bug didn’t reinstate any friend connections that had been broken, and highlighted that 83 per cent of people affected had only one person they had blocked temporarily unblocked.
Thankfully, the issued has now been fixed and everyone has been blocked again.
Ms Egan added: “People who were affected will get a notification on Facebook encouraging them to check their blocked list.”
