The most important rule in the ladder competitions is to not cheat or lie. Play fair is all. For each match there"MUST" be Ladder moderator watching the fight to make sure the fight is legit, no noobing is happening, and there is no cheating going on. Also, never discourage future matches, if you are caught demoting your next opponent's skill level or such, that will not be tolerated. If you break the rules punishment will lead to not being allowed to compete in ladders for a period of time, or losing the privilege all together.
