Someone hacked my account

I was about to join my tournament, but when i clicked the join button, i wasn't able to join. My friend then told me that he saw a label that said "This player has Violated lichess terms of use" or something like that. I was confused. When i asked someone else, he showed me tons of games, that moved the exact same moves as the stockfish bot. But the thing was, i never even remember playing those games! I have a feeling someone else played them. Please figure some way to fix this, and please take off this label.

@lichess pls help him

What if the hacker comes back it would be unsafe to remove the "This player has Violated lichess terms of use" from your account since you could be hacked again.

@SavageCabbageYT I see a lot of games you recently played were in team tournaments, do you remember playing in those team tournaments? Look at lichess.org/account/security and see if there were any sessions you didn't recognize. If you saw a session you didn't recognize, go to lichess.org/appeal and show the lichess team that you didn't violate the lichess terms of service.
Good luck!

Please see lichess.org/contact#help-appeal

Also, maybe change password and check lichess.org/account/security and do lichess.org/account/twofactor if you think someone else have access to your account.
