We haven't told you why he was banned because it was entirely internal and does not need to be otherwise. Please note that "power amuse" is generally not "entirely internal", and that we have been fairly straightforward with explaining people who were in fact removed for that reason.
Yes, other users that were banned by Vox have been unbanned. Other users that have been banned by me, Fish, hampa, veb, etc have been unbanned. Unbanning is occasionally quite normal.
As an aside, perhaps you should consider Fish's answer to be less "why you were banned in the first place" and more "why you're still banned on that account".
As a further aside, if you would like to continue this discussion, drop a word and I can re-enable a Gorm[a-zA-Z]n alt of your choice in Ban Appeals. It'd be nice if this thread didn't get derailed for this.
