>It's odd that it would be 1 out of 6 or 7, because when high elo streamers like Hikaru or Chessbrah are doing speed runs, they very often go on a 100 win streak, which sounds exceedingly unlikely if the odds of facing an engine user would be 1 out of 6/7.
I would guess that even with the engine you would take some games to rank up to that high so if chess.com is good at banning cheaters most of them would probably get caught sooner.
Yes, but those streamers often start from 500-600. And often when they do actually face those cheaters, they have gone undetected for 100+ games, maybe at 2000 elo, and they seemingly only get banned because of the publicity they face against the streamer. Meaning chess.com cheating detection by itself hasn't managed to detect them for so long, and who knows how many are there wild in the open managing to do more than 100s of games, without facing any publicity and doing it a lot more intelligently than the obvious ones against the streamer.
