I seem to recall than in MTW, whenever I hosted, if someone was cheating I would get a message. Then I would kick the person. I see no purpose in cheating, its just dumb.

But, there is a difference in cheating and someone being really good. I should now, i was called a cheater just because I woppeed 3 guys in the same battle. LOL that was my greatest mp victory, after that I went 15 straight games without losing.

So my point, not always is someone cheating it maybe because his/her is good at the game.
