I agree with Azontr, we've already dealt with him and we shouldn't need to clog up the thread any further.
As for whether or not a permaban is too harsh, I was originally considering 6 months to a year, but he self admits that a permaban was something he was literally trying to get, so I might as well apply that. If he comes back in about 6 months to a year on Community Central and politely asks then, I wouldn't be against lifting that once that does happen. But for now, a permaban is something he requested to happen, so I'd honor that. As usual, Antvasima usually questions of a permaban is too strict, but if he sees the part where "He wants to be gone forever", I'm sure Antvasima excepts the permaban via user request at least. And he's probably going to agree with the aforementioned compromise.
I should also probably go remove some posts getting out of hand or may have come off as overreactive or are just plain derailment.
