Cheat Prevention -- exactly what does it prevent?

[tinkthank]

I read those threads on "spyware" and whatnot, but I didnt see this question addressed.

Against what does "cheat protection" (I think that is what that is called in Game Creation) protect?

I mean: How can you cheat in this game? Is there something like a "maphack" (like in Warcraft) circulated? (Never heard of that.)

I cant understand it. Obviously Illwinter thought it was important enough to invest much time in developing, since they introduced this feature at the cost of many known bugs that have not been addressed -- but I couldnt even begin to imagine how "cheating" in this game works, let alone the vast multitudes of players who have complained about it (where? when?). But maybe I dont play enough MP.

Thanks in advance
