Who is going to bring some sunlight to the forum?
Eh. This forum has never been bright and sunny as far as I know. And frankly I much prefer one that keeps blackout curtains nailed up against the windows, as those are much more fun.
Well, at least he found P&S - he'll blend right in among all the other nutjobs.
I didn't even look at homeboy's posts, but if he's actually mentally ill I'd tend to agree with you--P&S is the right place for him (got that section on ignore, so I don't have to deal with the crazies). Better to keep the bitcoin and crypto-related sections free from insanity. As it stands there's plenty of that to go around with cryptohunter and his alts and a handful of collaborators. No need for more of that.
Technically he is banned forever (permanently) but that doesn't prevent him from creating new accounts and making a few posts before getting banned again. He'll get bored eventually.
One can only hope. Most trolls burn themselves out within a couple of months, but with the ones I've mentioned above, they've stuck around for much longer than that. Hopefully this particular one will just be a one-hit-wonder and grow tired of bitcointalk.
