First time I heard it is more widespread. In that case, I don't understand why Niemann is being targeted so hard by chess.com (no opinion about Carlsen.) Biased source in this case, but https://www.chess.com/article/view/online-chess-cheating https://www.chess.com/article/view/online-chess-cheating says 10%, which is certainly more than I would have thought: > Of the cheaters we have detected to date, 51 (10.2%) are grandmasters. 98 (19.6%) are international masters, and 160 (31.9%) are FIDE masters. More than 90% of these players are male.
