If he is permanently banned on lobby, that usually means that he has no chance of his appeal being accepted unless it was for advertising (It would say in the ban message) EDIT: By the way, I suggest you don't let him use your account otherwise you will end up perm banned as well.
If he's perm banned from the server, its for a good reason. And there is little to no chance that his appeal will be accepted.
Your questions have been answered in the appeal that was posted. I am going to be closing this because its handled.
