I do find it hilarious how two very high level players have a similar history of online cheating, and yet they receive completely different treatments

Yes, I am talking about Hans Niemann and Sindarov.

Both have cheated online in the past.

The former got bullied throughout their career for it. As for the other one, most people have forgotten about it, or don't even care.

If this does not prove chess community's hypocrisy and shameless Magnus cock-sucking attitude, I don't know what else does.
