As the guy who re-bumped the "Let's talk about" thread, I personally had problems with his unnecessarily inflammatory attitude, and instead of fixing his attitude, decides to troll other popular "bad posters" to avoid being lumped in with one of them. I've done some research myself, and he actually seems to be a legitimate poster who isn't underage ban (like Guntaker or probably Murica), so there is hope that he'll change. If he is taking a sabbatical and changes (and by that I mean takes a rip and chills out), I'd welcome him back. Give him a few years and he might not be a bad poster, tbh.
Not every high school poster is going to turn out like SWE or Flo.
IIRC he claimed to be a professor, which is not completely unfathomable given his detailed knowledge about certain subjects, but exceedingly strange in other ways (ex. his repeated insistence that slavery was big in Eastern KY and citing maps that showed the opposite as evidence.)
