Not to kick a dead horse but stlhobby had a similar problem. To get on the board you had to be "verified" by two providers. Some people - both hobbyist and providers - felt that was some sort of "proof" that all those members were safe. It was not. There were guys who were blacklisted on another board and on national blacklist sites for stalking, assault, rip off, attempted blackmail, and other problems who were "verified" members there.
The same misconception could be happening with RTP. As far as I know to get "verified" on RTP all you need is two providers to say they saw you. Now RTP could refuse "verified" status for those on blacklists but then RTP is at least indirectly letting the hobbyist know he is on a blacklist. The blacklists loose their effectiveness if the person on it knows about it. If a hobbyist knows he is on a blacklist he'll just change his email, phone number, screen name, and go by a new alias.
