constant banning of my account without any reason

I didn't even know that users can do this. I hope the reporter gets banned.

Uh...reporting accounts doesn't ban them. If it did, lichess would be a giant ban war.

I hope this person gets banned. Maybe it is someone who knows you?

well, one of them was the rival quitting, lololol, and the other one was connection lost, which can happen sometimes to anyone... You should find a pattern, not just an isolated example that is driven by an exogenous and uncontrollable random factor. I have never been reported in my whole life and this week it´´'s been three times, sometimes without playing, as today
