If I report someone, what's the process lichess uses to determine whether they cheated?

I have a suspiciously good game coming from my last opponent, 0 blunders mistakes and inaccuracies, and even knew 5. Na5 in response to me attempting the Fried Liver attack. Also his first few moves took suspiciously long

However, his rating lacks a question mark, a cheater would probably rank higher than 1300, and his previous game was a loss.

I am afraid that bans run based on report count, so I'd hate to add to that, if so. What happens if I report somebody?

-Irwin looks for play characteristic of chess engines: github.com/clarkerubber/irwin

-Kaladin looks for play uncharacteristic of the players: github.com/lichess-org/kaladin

the process is lichess calls their mom and lets them know their child potentially cheated.

I wouldn't worry about an opponent playing well in the opening, especially a 1300 player knowing how to defend against the fried liver in particular, since they probably have faced it countless times as it's one of the first openings taught to beginners and low rated players, and if they got sick of losing to it might have studied it.

I have no idea if your opponent cheated or not, though. I think playing well in the opening isn't a reliable indication of cheating.

also if you get a bad position in the opening, it's really hard for you to play accurately because you might have only 1 good move that is hard to see, whereas your opponent might have 10 good moves that are easy to see.

if they did cheat, they must be the worst cheater ever based on their rating, but, there's no harm done in reporting them to them or you. I don't think report count factors much. the only harm would be if you report every loss. then the moderators might ignore your reports.

Bans are never based on report counts, that would lead to an incredible number of false positives. If you report someone, your report will be put in the moderator queue. Once it reaches the top of the queue, a human moderator will look at it.

This would be the typical case at least, but there are a couple of exceptions.

I am very confident that no chess site uses report count as decision criteria as normal player cannot know if someone is cheating. Regardless if they think they can do it or not. It must be based on statistical evidence on being able pull really good moves suspicious ways. As what exact process is : it will remain unpublished as publishing might allow making a cheating method designed to by pass it (emphasis on might)

As of you specific sample. Knowing Na5 does not indicate absolutely anything.

Thank you.
I think I'll wait a couple days and look back and see if there are any other suspicious instances, first. Only some of the moves seemed hard to find, when I looked back.
