here's a thought

sign on as a guest (especially underage) - insult people - get kicked out of the room - go to another room and carry on as before - get kicked out - go online the next day and carry on as before - no problem!
sign up as a member - question the views of one of the admin and everytime you try to get on it's 'you are banned'??
seems to me that it's better to be an abusive guest than join and commit the one off cardinal sin of questioning admin!
the rules are - cause grief to to other room members, but don't ever question the attitudes of admin!!
could it be put into chat rules that you never question admin? that way people may not fall foul of the rules they never bother to read anyway? if only i was a 14 yr old **** offering dirty chat i wouldn't be banned!
