I'm really getting angry at them. They make my safety rating go down. What should I do?

If it has a forum, save a replay of them doing that and post it.

If the server has an InSim that has a safety feature, they are bound to have some sort of banning system, like JPeace + zeugnimod said, check to see if they have a forum and tell them there.

I'm going to give you a warning warning warning..

In rallycross, when I was at the first place, the second guy got mad and crashed me to wall.

On PVL Crash 'n Fun 1 or a proper Rallycross server?

Since real rallycross I can barely find on demo.

Though most demo users, and I don't mean the ones posting on the forums, are very rude, are crashing, complete nubs, banning for no reason, and more.

This just makes me sick every time I join a demo server.

I'm even thinking about making my public server a public demo server just so demo'ers can have clean racing.

Please tell me if this is a nice idea.
