You can't convince me otherwise, you can tell whatever you want, but players with rating below 400 can't be playing like prime Magnus in the blitz (which means lower time to move, so you expect more blunders, but nope) with accuracy ~80 almost every second game you play. And it's impossible to play and up your rating, because you know once in a 2/3 games you will get the cheater and your rating will drop. It's so annoying. I literally checked the every game and sometimes even live (I'm moving myself, just seeing what the computer will suggest for the opponent after my move and guess what move they're taking most of the times and I'm just not playing if I see the person moving like computer), and opponents move exactly like computer suggests, def cheaters, I report them but the site administration doesn't do anything about that
