Naroditsky played a match against Magnus that he streamed where it ended (this a 1+0 time control; yes you can cheat in bullet but it's clear he wasn't) in a 40-40 tie, this after he lost the first game from being distracted getting his stream set up properly

He was one of the world's best bullet and blitz players, it was obvious he was never cheating. Kramnik was apparently one of his heroes. It was despicable behavior
