Dude ... crusader perma banned him and it was his case ... why did someone else change it? It's crusader's job to unban for his cases, not someone else's. Also, this just adds more confusion D:
He was ban from this http://skyblock.net/threads/crusaderboy1-please-unban-me.7068/ don't try to hide it and fake it.
I actually went onto the server to check, and found that he was banned for "Flying", because I shared the same suspicion as you. No he isn't trying to hide it, but there is something wrong happening to this case ...
