perhaps, but then again why can't they just use a system similar to Valve Anti-Cheat?

advantages
 * random delayed ban time makes it hard to tell when the program has been compromised
 * a game of psychological warfare straight out of The Art of War

disadvantages
 * takes a while for the system to be really effective, it's more of a long term advantage
 * hacks will be out of control for a few months to a year

now I'm not sure how the current ban system works (ban on sight? ban a week later? or random ban time?) this is a possible option
