who would mooza be though? There's not a perma-banned guy on that list I would put my money on who is that much of a Murraytard.
It could be any of them really. When you're online, it's not that hard to act like someone else. Hell, it could have been Fed's mate again (like with his other multis like Brentos and Lembras).
So it's either that, or scoobs forgot to put Mooza on the Banned User list.
