Yes, you're right that being public doesn't generally mean it gets detected often. But for rust at this very moment, it very much does mean that. I've played legit for 3 months straight with aimbot and esp without getting a ban once(that was in spring tho), I've never been actually manual banned because I know how to play the game and actually decently aim without an aimbot. Manual bans generally get placed on noobies who haven't played the game before and don't know how blatant they look. I don't know what "private" cheats you've used but I can't say the same with my experience, kinda looks like you got scammed by thinking it was exclusive lol.
