This is based on luck actually… I have like 80% of my accounts back using this method.
It’s pretty simply. If you’re using Massplanner (and you follow my advices/settings…) then you should have your Backup module run before. So your profile picture is backed up with Massplanner.
Now use your profile picture, save it as .png format and upload then wait for Facebook to approve. 80% of my accounts are back after this.
Actually if you’re able to save the longest used profile picture which shows the face, it’ll be 100% unlocked within 2 days.
What triggered this? I honestly have no idea. Even my own personal account has this issue. Even accounts with no actions at all triggered this checkpoint. It’s pretty based on the “trust” level of the account but that’s a wild guess.
