I can't speak for FitnessBoard because I don't think I'm a member there.
As for AnabolicBoard, I'm there pretty often and it seems to be okay. However, there are a few bros that I don't see there anymore. When I asked about one of the ADMINs, the question went unanswered and nothing was said about it. Also, AB is mentioned in one of the Raw Deals indictments, according to a San Diego news media. So as far as I know about them, we are very very careful what we post right now.
As it stands, I would just be very careful where you surf and what you say/post on them. Stick only with the boards that you are very familiar with, spend time at, and where you know everyone. I've already seen some new names on some of the boards and they would ask obvious questions. So far, I've seen 4 great boards mysteriously fall off of the internet in just 2 or 3 days. I was on AnabolicMind just a day ago and posted on it but now, it's gone. I don't know if it's a server matter or if the ADMINs are shutting down until this matter blows over.
