Recently, one of my friends' bitcoin talk account got banned without any reason. He had earned 3 merits for his posts. He felt very bad about that.
So he didn't feel bad about being banned, only about the 3 Merits? Let me guess: he can easily create another account, but getting more Merit is difficult? Just to be clear: creating another account to post anywhere else than in a ban-appeal thread is not allowed after a ban.
Those Merits aren't lost, they're still used to highlight good posts.
