When in a real race somebody does something out of the rules, it is reviewed and investigated by race authorities
So do we. In real race, if some racer takes revenge what happens to that revenger?
If you don't inform admins that there are people who drive like an idiot, most of the time we don't know. If you are ingame and there is an admin ingame, he will respond if you report something is happening and will watch that racer or the replay. If no admin is active, you can use TeamSpeak or this forum to tell what happened.
That is the way it works. We depend on our racers to see what is going on. Having admins on a a server does not mean there are eyes watching everyone and everything all the time, it isn't even possible (also because we race as well).
So, in short, our policy is: racers make the races. Admins are just available if things can't be sorted out between racers.
Or even shorter: our racers, and also you are our:
eagle eye
If you think someone is being bad, talk to him. If it doesn't help; use an admin or the forum. But don't revenge. Because it adds nothing, improves nothing. And yeah, revenge wrecking has a standard of 90 days.
