banned me on lichess. Lichess blunder, Why banned?

hello :)
I got banned in lichess rapid arena (2018 annivecary).
probably this is a lichess blunder, because I make mistakes and I can't "Cheating".
My name is Edward Helaszek, I'm old. I playing mostly King's indian or queen's gambit; sometimes A00.
I don't have a title in chess. I have my country title and that's: candidate .
Please do not writing"youre cheating, youre bad". I play on lichess corresponcence games and tournaments blitzing and rapids.
Maybe i must write to contact page. Tomorrow I go to other country and I can't answering.
In analyze, I have mistakes.
I don;t understand why I am banned on rapid, I got always berserk, in other tournaments (blitz shield, superblitz shield) I never gonna banned.
In Blitz Shield I got 13 place!
Cheat isn't good. Sometimes I think, maybe I have "cheating head;".
If I'm gonna Twitch account and OBS I can streming.
This decision about banned mostly draw player in tour RAPID ANIVERcery is woirld.
GOodbye, I can answer in every moment.

It was obvious you were cheating from your move times. I am surprised you didn't get banned for this long
