Of course they are now justifying with it the red tags they are giving and destroying that account.
He is tagged because he bought the account which he admitted - not because he plagiarized.
Anyhow, he is not banned anymore, and I think theymos was more than fair to him, he can probably defend himself now, in the right section (reputation)
After looking at the logs, I find it likely that this story is true, so it wasn't him personally who did the plagiarism. Trading accounts is strongly discouraged, but not against the rules. Therefore, the ban is removed.
