Well , i agree with u dgromov, features like flying or fast runing , shouldnt be (BUT i dnt agree at the part that these were the problem, no, the detection isnt based on the features, doesnt matter what features u have)
But i would say it more like this : the cheese wouldnt be detected by players , detected meaning, they wouldnt see you cheesing, and report it (recording u flying and others...),
so let s imagine the cheese is up , if ppl do less reports , devs will think it s getting better and the anticheese wont get updates any sooner...
