Chess account marked

Hi, all. Now most people would not admit this but, the account liamzink1 has been marked because of “cheating”/sandbagging because of me. I was asking him/her/non-binary unit for a rematch and each time I would play around 5 moves then resign. lichess has now marked that account, when it should be me. Can someone please help or talk to the moderators or at least lichess know. I have tried multiple times. And they keep thinking that they were cheating
Thank you
