I think the analysis is pretty good at pointing out big blunders and offering chances for you to improve by retrying the move. In this position from your last game, your rook is hanging. Your move didn't address that problem.
There are at least a dozen places you could look at the analysis and possibly learn something.
As far as Cheating Detection methods, Chess.com doesn't reveal that. There has been a lot of publicity recently related to it which you could certainly find without any difficulty. If you want to discuss it, you have to join the Cheating Forum club.
General opinions and advice would be nice.
I've had this account for years but I haven't used chess.com in quite a while. However, I have been playing daily, for about an hour a day, on lichess, for a long time. I'm not a strong player - just a beginner. Don't have any use for autistic stuff, but the chess analysis thing here might be of some interest to me if it helps me to become a stronger player. Not if it's just a little man in the corner of the screen saying "well done, good boy" though. I can see how that adds to the fun, but it's also a bit exploitative of autists and the like.
Oh, and another thing. How bad is the cheating problem here? Long story short: lichess seems to have quit dealing with cheats some time ago, and cheats (people using engines) make me furious (which is the real reason I'm a refugee from lichess). The insta-move thing where it's obviously automated is easy for a system to detect, but the regular sort (where the player takes longer pauses after making a mistake to consult an engine, then miraculously turns the game around and never makes a mistake in that game ever again) is a real scourge.
Thanks
