I don't see how you can really cheat in esf... an aimbot that follows someone when you swoop is maybe the only thing, but that's not even gonna be worth anything in 1.2. Same with beams.. it takes awhile to get there and they can teleport, pretty worthless...
Like hybrid said, you'd do better without it... So I don't think you need to worry.
And just my opinion, I doubt the guys that create the "hacks" for CS would do them for ESF, how many people do you know that love and play cs so much that they design hacks also play esf?
