I used to mess around years ago in CS 1.6 with public cheats mostly just the rage aimbots with speedhacks etc, then I moved CSS and got VAC banned quite a lot so I eventually found a cheat called KGCheats which never got me VAC banned due to the Ring0 security (The patchguard disabled stuff), after this I moved to CSGO and now I am currently cheating in Rust
Edit: Forgot to mention I also cheated quite a bit in TF2 but never really legit because I did not take that game seriously its always fun to annoy the kids in that game
