Today a friend of mine told me that he used texture hack. I'm not sure whether he used it for experimental purpose or to cheat. So, my question is, how was he able to do it? aci didn't ban him?

So aci detects texture hacks? And i hope my friend is server banned if he used it to cheat.

Texture hacks aren't detected by aCI afaik.

texure hacks cannot be detected.like the skins of the game, the texures are client side and not checked by aci.Aci detects programs that need to be injected into the game.

Sad. But now my confusion is cleared. All those hackers were using texture hacks. There are no hackers nowadays because they're all banned.
