All of that could of been easily photoshopped. Nobody on an internet forum could/should be SO SERIOUSLY invested in a forum that if somebody hacked into it they would develop false information to get them on the FBI's most wanted list. Even if they were to do that, the forum moderators and anyone else involved could be sued for every penny they were worth and also arrested on several felonies for making up such a dumb story trying to ruin a kids life for hacking a forum.
So yeah, I don't believe this is true for a second.
