I was playing on another Chess website (chesscom) and analyzed a 6 month sample of my games only to find out Chess.com banned as many as 20% of the players I played against for Cheating (I ended with closing my account in pursuit of another Chess website with not as high of an infestation of cheaters) which came out to 1 out of 5 to 1 out of 10 players using an engine during play. Not too surprising given the ease of availability and the lunacy of "that section" of the population. Also is worth noting chesscom banned more than 250 titled players from their own website for engine-using as of one year ago.
The overall message to the cheaters: go play solitaire!!!
