I don't think we need a new sub for this, especially as Meta would be pretty empty without them,
Would that be a bad thing?
It wouldn't be empty, we could still have 50 threads about merit here, and of course the threads about other child boards that we would like to create.
I like CB's idea though, whether we create a child board, or a single megathread for appeals, or leave appeals in Meta:
they should also have the privileges of using their old account to appeal their cases
It seems kinda pointless to force them to create a new account. The ban message could have a link to Meta/child board/megathread so they could just go and post there (but nowhere else).
