I don’t understand what evidence is needed that the player is a cheater? Even if the player has a score of 100-0, he is not a cheater, there is no evidence of what kind of nonsense? Or is the admin covering cheaters?

One, no evidence, no ban. Two, you need to provide Evidence of cheating. Prove it to us, not to yourself.

Three, you need to find their soldier page, using search, and hit "REPORT". IF YOU HAVE NO EVIDENCE, DO NOT REPORT THEM.
