I have no problem with it as long as he acknowledges he was wrong and is treated the same as everyone else who has been banned and unbanned, if he starts falling into his old ways which lead to his permaban the he gets banned again.
It has been quite pleasant without his billigerent attitude and bad forum etiquette intruding so if he can control himself and refrain from his previous antics I see no real issue with him returning.
However, i do not believe he should be reinstated as a Moderator, imo he just is not suitable for that position as I'm sure those who had their personal details abused would agree.
i personally think he should be given one more chance.. i know what it feels like to be left out of our community. we all owe it to him to give him just one more chance to prove himself that he can thrive with us here.
