I watch Levy's youtube channel, and he is certainly not the kind of person to vindictively report someone because they beat him. Furthermore, he explains his reasoning clearly when he thinks someone is cheating using a bot: they make strange moves, the time between movies stays fairly constant, they take longer than expected to make very obvious moves. I would be very curious to see this indonesian player legitimately play against a chess master live, because from both chess.com and Levy it sounds like he was definitely cheating.
