Nobody is arguing with that GotNoDigits, it is the deliberate trolls we are concerned with. Some guy decided to jam me into the side of the map, would not communicate, I had to kill him in order to move! Apparently it's just *my* actions that are unacceptable.
The in-game reporting sounds like the best system. Any automated system can and will be gamed by trolls, and if it already exists then it should not be hard to implement...
