Your ban is from 2019-03-07. It's a bugged netid ban, so we don't know what the stated reason was.
But before that you had two more bans. The first one from 2018-12-02 for about a week for team killing and trolling (player name DoubleTrouble). Then, on 2018-12-16 a 24h ban for disrespecting admins (player name SingularTrouble).
And I also found additional info in our watch list
here and
here, for when you were playing as Meta Physics Breaker. (links are accessible by admins only.)
Your ban stays.
