Anti-cheating doesn't seem to work

Hello everybody! My name is Eddie. Lichess is a very nice chess website with great features, some very strong players, and some very fine people I feel.

Cheating is the most existential threat to online chess and needs to be taken seriously.

About a week ago I reported a player for fair play violations. Unfortunately, he has not been banned despite it being a very obvious case.

He registered his account on the 27th of November, 2025.
He played 52 games.
One of those games was a bullet game which he lost.
All the other 51 games are rapid.
His first two rapid games he lost, against 1195 and 1022 rated players.
Since then he has won every single rapid game he played, 49 in a row.
Out of these 49 wins, he got (according to the Lichess analysis)
1x79 percent accuracy
1x 88 percent accuracy
1x 94 percent accuracy
1x 95 percent accuracy
3x 96 percent accuracy
7x 97 percent accuracy
13x 98 percent accuracy
19x 99 percent accuracy
3x100 percent accuracy

I have no doubt that serious professionals are working for the anti-cheating Lichess team who give it their absolute best keeping the site as clean as possible. In my opinion, though, it is frustrating and disappointing that even such obvious cheaters are allowed to stay here and destroy the playing experience for us decent and honest players. I am wondering how much more obvious it needs to be for players to get banned. What am I supposed to do?

Entertain the ridiculous notion that they might not be cheating. I have played multiple games in rapid with 95+% accuracy. And most of their games end in less than 30 moves. Due to their opponents' blunders (which they took advantage of).

I get your point. But from losing to 1000s to - a few days later - beating 2000s with 99 percent accuracy ... in what world is this believable? I am a reasonable man.

In a world where tilt exists. Back in October I defeated a 2480 only to lose to a few 1800s the next day.

I appreciate your replies. But there is no tilt severe enough to explain how someone goes from losing twice to 1000s to going on a 49-game winning streak with 45 of those wins being at 96 percent accuracy or higher. Even super GMs would probably not be able to pull it off. The numbers don't lie.

You speak from experience? Because it looks like you don't have much of it.

I will not respond to your comments any further. You try to offend me on a personal level and I am not participating in any such conversation. It seems to me you feel the need to make excuses for an obvious cheater. Thank you for your comments. I wish they had been more productive.

Yes, this is so funny.

"Cheating is the most existential threat to online chess and needs to be taken seriously." * Yes

"I reported a player for fair play violations. Unfortunately, he has not been banned despite it being a very obvious case" * Then it was at least not obvious.

"I have no doubt that serious professionals are working for the anti-cheating Lichess team" * They are volunteers

"such obvious cheaters" * Not that obvious, or he would have been banned.

"how much more obvious it needs to be" * Conclusive evidence.

"What am I supposed to do?" * Report and wait.

You only played 1 rapid game, so it must be this one.
