Yesterday I played a SnD match. We lost, but I didn't notice anything out of the ordinary.
Today I received this mail that a player (who joined late in the game) got banned for 10 years for violating the rules.
Out of curiosity, I went back and watched the game replay. This guy was playing very passive (camping, holding angles), so he got lucky timing a couple of times. But he certainly didn't know where the enemies were.
He nearly lost all the gunfights so wallhacks/aimbot are out of the question.

Is there a sure way to know the official reason behind the ban?
