Garry's Mod

Now I'm very aware of what's going on with all these VAC waves and stuff on CS:GO; I understand Garry's Mod doesn't run VAC and that they use other anti-cheats. (My friend codes LUA and I would use scripts >.>) However since this cheat would be modifying game files a VAC ban is very well possible. I know if you use if you use BaconBot (A LUA bypasser) you can get VAC banned from that and other presales questions I've read, people say VAC is disabled. I would like to buy this cheat but I would like to know when the last VAC detection were on this game :)

GMOD hack was never detected
