How Do Lichess Detect Cheater?

I dont think lichess automatically detects cheating at all unless a bunch of people complain about the same player.

I play at 1200 level with a caveat but I see a lot of consistent 2000+ level moves and strategies from 1100-1200 rated chess dumb...es.

edit: I didn't realise this thread was a week old and was bumped recently.

I thought it works like this, but I could be wrong.

after a player gets flagged for cheating, the last 10 (from memory, it might be more or less) games they played are refunded. What I think (and might be wrong about) is they don't check or care if there was cheating in all of the refunded games, it's just a blanket refund of the last 10 games played.

so potentially someone banned for cheating played you but didn't cheat against you (if what I think is correct)

it's the last 40 games, see https://lichess.org/faq#rating-refund

How do you think the "cheat detected" works?

IDK, algorithm that checks every game automatically upon completion?

No, it checks when the game is in progress.

I recently played a 1600 rapid player who destroyed my modern opening 1...g6 with a 7 centipawn loss.
Not surprisingly since he was banned soon after.

I didn't even have time for the report.

If someone cheats in a way too obvious way they can be caught by low level automated detection and requesting a computer analysis can be enough
