simple question : have you encountered an anti-cheat mechanism that works to stop cheaters?
I haven't.
The damage that DRM causes is almost entirely one-sided towards the consumer, aside from the pocketbooks of executives that want to boast about their games licensed anti-cheat mechanisms.
Those that want to cheat may be thrown through another loop, but it doesn't meaningfully stop them -- these people are often technical and interested , anyway. A new challenge for credit on underground forums -- great!
