Facebook revealed last Monday that a bug on its platform had temporarily unblocked previously blocked users, allowing them to send unwelcome messages and exposing hidden messages as well.
The bug, which was estimated to have affected 800,000 users, was quickly fixed. However, it marks another misstep for the social network which is already under heavy scrutiny for its string of privacy errors. Facebook, however said that only one person on a user’s block list was temporarily unblocked.
In a blog post, Facebook’s chief privacy officer apologized and said that the company knows that the ability to block a user is extremely important.
