Recently there has been a significant upsurge in a thing known as flamming.
This is when people within a forum start getting angry at, or offensive towards other people, and is getting to an intolerable level.
I am now going through the forums, removing comments of such nature - somewhat against policy of free speech, but if you don't want it to happen, maybe you should think twice before you post.
If some of the persistent offenders continue, it wouldn't take much to introduce a temporary or permanent ban on your account - its happened before, it can happen again.
Update:
If you need to report something, the link in my signature should take you to the emergeny centre... other members of the police, I'll pm you the link.
