I was personally only trying to defend well... my whole gender.
3,418,620,594 women live on earth actually so 34,186,205 are usefull according to this guy (I supposed it was one).
Tell me about it. I lost a forum because of such a situation! I was running a general discussion forum and one contributor was a troll who liked to cause trouble. He was tolerated, but disliked. He finally made a comment about the Soham murders that I felt was way over the line, so I -not for the first time- removed his message. He became abusive, so I banned him. Unfortunately, most of the other members felt I should have left the message up, said they didn't like being censored (only one member ever was!) and they left.
I always felt that the operator of a forum very soon isn't the owner anymore.The people using it create a climate of their own and as long as the users don't ask for restrictions the operator (which is in most cases the admin & mod too) should use his special rights very carefully.
