Nikolay, in my tournaments we had 4 or 5 accounts closed by chess.com. The number of entries was about 700. Maybe 300 individual players because many players played in more than one tournament. These figures are approximate.
Of the accounts closed, one was overturned on appeal to the CFC, one was a false-positive and the rest were new players who subsequently disappeared. I don't have enough confidence in the cheating detection to put my name on a public list accusing anyone of cheating.
