Before you all start debating that how can one cheat in bullets, listen to me. It is possible to cheat in bullets where engine makes moves for you and in this accuracy can also be pre determined [Don't ask such engine from me as I don't cheat].
He joins server on 5th May and claims that he is rated too high on lichess. Why did it need to tell so? Just to manipulate others that he does not cheat.
He plays rapid get a decent rating and then blunder queen in 4 seconds. I don't think a 2000 to do so.
He plays several games and reaches 2000. VERY FUNNY TO LISTEN...
And if you ask for why is he not caught by server then there is a video on youtube that how to cheat without getting caught by server.
So, I ask you all to give your views on it, and if you have any fact or proof that he does not cheat then comment it below...
