I totally AGREE with you that there is a big problem with online cheating! Often the degree is overstated but even with reasonable estimates - it is still a big problem. OBJECTIVE cheat detection is a non-trivial problem and you really need to set high limits so that you avoid false positives.
I definitely do not think that starting with the Kramnik SUBJECTIVE detection approach is the way to go. He is suspicious of everyone (a bit paranoid like many top chess players who worked so very hard to get to the top) and subjectively focuses on people who beat or drew him or even give him a good game. It is silly to make many dubious reports like the two K's that are pretty much all unconfirmed. If you play Blitz (or faster) especially with no increment there is lots of room for many random upsets due to the number of mistakes inherent in these type of games.
Yes, some people cheat during the titled Tuesday events. The big need is an objective answer to the 'Who is cheating' question and that means that you need a sample of games unless the cheating is blatant / simplistic. You need to sets high limits to avoid false confirmations. Suspicions are one thing and strong statistical confirmation is another. Aleireza was apparently flagged on cheesedotcom when he was very young - he denied. He was given an test during a video conference with positions to solve - his performance was jaw dropping and he was cleared.
With chess, we are unlucky with the existence of such strong free open source chess engines and the nature of our game. With a cheap phone and and a free chess engine app, anybody in the world can beat all the top twenty human players easily and also slaughter the world champion. Imagine if in tennis, someone could get a free app and then proceed to obliterate all the top players - not possible with tennis but with chess it definitely is!
Cheers
PS: The Perpetual Chess Podcast had interviews with several professor types who are involved in cheat detection with mention of some specific cases. There was also one with a guy (cannot remember his name, will check) who used to work with cheesedotcom and some interesting and surprising things to say about cheating there.
