While probably bordering on morally wrong, I suppot random here: in FWN, yeah there are good people, but they decided to join a clan of idiots. Generally unless you are IN FWN or you just like them for whatever reason, I think it's fair to say when an FWN user joins ANY server, it suddenly gets dumber by a huge margin. And like random said, if they have some intelligence to themselves, they can irc them and he can un-ban.
Thought personally I wouldn't have the patience to ban them all.
