So i've tried it on loads of servers. Some I can name of the top of my head are: rebornroleplay, grandtheftarma, code4gaming Koth servers. I've also played on a lot of random servers e.g. CQC servers. All of these servers did not catch me cheating. As long as you cheat legit and don't do something too weird no admins will watch u and u should be fine.
