I move they make it so:
When the game detects a player with an unusually high Kill/Death ratio, put up a vote to ban the player.
If passed, the player gets KICKED and BANNED from multiplayer for an hour AND the game automatically restarts (no waiting).
If there is more than one cheater, keep repeating process until everyone is removed. Meanwhile the non-cheaters keep their points. (not score, the other thing)
This is for COD World at War and COD4
