A facebook group with 6 admins is being hacked. I suspect that one of the admins has accidentally allowed someone to get their password.
The hacker comes in at night, using a username that is not an admin, and not in the member list. They delete everything - all threads, all posts - then disappear.
That sounds to me like they are changing their name while online and within Facebook, so no one will see that they are using a specific admin account, but that's just a guess.
Facebook security is a joke.
Facebook has no way (that I can find) to even report it. If I could report it, I would have a chance to get Facebook to look in the database log. The FB database logs would certainly have the IP address of the hacker. If I could get that, I would file a criminal complaint with the police.
Anyone have any ideas?
