Can cheat detection be contested?

I get that I shouldn't have opened analysis board, but this is the position I entered into the analysis.

It's obvious that I would have won regardless. The only reason I decided to open analysis at the very end (when I had three pawns and he only had a king) was to tell whether it was even possible for level 8 AI to win in that position, and because he was letting the timer expire rather than resigning, so I got bored.

First of all... What was that opening? Messed up!
Second of all... You shouldn't have turned on analysis - Just do some puzzles if you're bored. Seriously, just wait a couple more moves!
But to answer your actual question... I'm not sure. I guess you can write 2 Thib.

@TacticalYokel you are not marked as a cheater. But yeah, you should never do things like that you described.

I didn't even know we could do that, lichess should make it impossible to open any analysis during a game.

@CafeMorphy it is impossible! Lichess can not do this during game because AI analysis configured only for games that end

Wow ok, I guess the OP did some special effort to check analysis during a game...
