So does hacking tbh... It doesn't require that much knowledge about programming to stop 80-90% of cheats out there...
Besides most of abusing bugs about the current files have been fixed by TwoStars already
So only hacks possible are speedhacking, possibly packet editting and tbl edit and ofcourse human mistakes..
2 of them require some knowledge but I'm sure someone is able to put up a basic anti cheat system.. last one is just not being an idiot and speedhacking sadly is veryyyyy hard to fix but it's harmless anyway
