If you "Banned" people are reading this thread, you have been caught breaking the ToS conditions!
More often that not, although i cannot confirm so, the ban has been for cheating!
Of course, you may create more accounts, but if you continue your bad habit, sooner or later you will be banned again!
Lichess detection does, sometimes not fast enough, works!
So, accept that you are not welcome, leave Lichess to the players who abide by the the rules!
YOU know why YOU have been banned!
I agree with
@Kostsov_Sasha , Stop posting "Why am i banned"!
