> These things do not prevent cheating at all.
Yes they do. They don't stop all cheating, but they raise the barrier to entry which means fewer cheaters.
I don't like arguments that sound like "well you can't stop all crime so you may as well not even try"
Ok, they prevent known cheats that the company has found online behind some subscription site run in the basement in Jersey. True. They do raise the bar, but they aren’t the barrier.
