They also claim 100 million subscribers, so that's 140,000 cheats. Since if you're cheating you probably do quite well (I pity the engine that could lose to me!), that's likely most of the high-rated players on their site.

And actually this tallies quite well with my experience of amateur physical sport, where at the lower levels everyone's honest and sporting and it's all great fun, but as soon as you get to the point where people are putting their heart and soul into the game, everyone's cheating, everyone knows everyone else is cheating, and anyone who's not cheating might as well give up and go home, as far as winning things is concerned.

Once you put money on it, and you're playing against people you're never likely to meet in real life, Jesus I can't imagine what it's like.

This number seems wildly low to me. I've been playing on chess.com for 2 years and have run into ~30 cheaters. I know they were cheating because chess.com told me they were. I've suspected a handful more of cheating who may not be as they were never banned. Either way this number doesn't seem correct.
