Re: how hard can it be?
as i said, esp and wallhacks are indeed very hard to combat. but speed hacks? comeon, the server sees your every move, it's a walk in a park to combat speed hacks.
same with aimbots, the client can communicate the enemy's location and the crosshair location to the server, the server can run a script that follows the crosshair's location relative to the enemy, and if the movement is minimal (close to 0) over a long time, and more than one fight, you can safely assume that he's aimbotting.
that's why in certain games, you only get 1-2 games with cheats before getting banned
