I believe the anticheat is meant for aimboting and aimlocking, which is quite nice and solves a lot of things the base game didn't address, I've seen far too many people getting instantly kicked from a server for cheating, which is a good sign.
But the wallhackers are really a thing that's becoming quite annoying, I've encountered quite a few and they just completely ruin the experience.
I would be nice if we could get an update that improves the detection of this sort of tools.
