Lol - because you get banned for not knowing how to excuse your temptation of raging.
Or you just cant ignore the fact that bullet tracking and headshot features are high risk features. Does not entitle you to claim a detection. Cheats can become detected yes. Is that out of our hands? For the most part yes it is; what we do is try to minimize that risk and if it becomes apparent that it is we rewrite the drives/authenticate new servers etc.
Sorry for your loss but that is the price of cheating sometimes.
