i used to have a chess.com account posing as the bot "antonio", and played with chess.com on one side of the screen, and a strong lichess bot on the other. i would always pick the opposite colour on lichess and just copy stockfish's moves and play them in chess.com against some randos. many matches took place, and not a single move i ever made on that account was my own.
i did it as an experiment, to see how long i could keep cheating, as i intentionally could not have been any more obvious. i kept doing this for months, ended up with an incredibly prolific cheating account hidden in plain sight. i noticed that the less i tried to hide it, the more successful i was (i've had many such accounts). the only people who managed to beat me were shitters with stronger engines than my own on their side, they were trying to hide it, and almost all of them got banned less than a dozen games in. some guy got banned right in the middle of a match and i won. however, i managed to get over two hundred matches in with that account, and saw a lot of autism in chat (almost 4chan levels of it), retards getting angry and intentionally delaying their moves thinking they're wasting my time, when in reality, i have no life, other cheaters getting banned but me staying in the green etc.
i took a hiatus for about a month, then came back, won another few games, and only then they decided to ban me. i tried it a few other times, with equally obvious accounts, and it seems like you can keep cheating in that way for as long as you want with a very slim chance of getting banned, so long as you don't make a hiatus and then return to that account. unfortunately, they deleted that account, as well as almost all others and now i only have one inactive account, empty called "antonio_the_man", which i honestly want to get back to. make some more chessjaks whine
