Well that is where members can help to be fair mate. We have had so many problems with the Troll, we have blocked many others who tried to register (and registration is closed at the moment again) but we can't tell all the problem posters. It is up to members to let Mama/me know if there is a problem. By pm is better. Rather than jumping into threads.
It isn't telling tales, or grassing either, it is helping keep the forum in line with what regulars want.
It does also mean being patient if and when we do re-open registration with new users to give them time to see if they are ok or not!
