People who are just trying to be good citizens of Facebookland, by reporting fake accounts set up by, say, a scammer pretending to be their dead granny, are being locked out of their own accounts by what looks like a glitch in Facebook’s reporting function.
Users frustrated at the lockouts had taken to Twitter to get Facebook’s attention with the hashtag #FacebookLockout. Some users said that for up to a month or more, there had been a Catch-22 loop, where reporting a scam account led to Facebook freezing the reporting user’s account, presenting them with a request to confirm their ID, and then failing to upload their ID.
