Like Hilariousandco stated earlier on, It can't all be done in one day. You have to be a bit patient.
I saw his ban appeal and profile a few days ago and i believe he may get a signature ban. Let's wait and see.

I believe Global Mods now have the ability to revert the Permaban to signature bans too if they  believe someone is worthy a second chance. Since there are so many appeals lately, i don't think only admin could handle all of them since he is so busy.
