^No direct matches, but definitely a jerk or a troll. My guess is that he's one of our old super-trolls, perhaps my favorite one. He's "insensitive" but fairly creative. Shows up every few months and starts a handful of usernames using proxies in different countries, each with its own schtick. Perhaps his most famous one was bombing a subforum w/ necroposts to plaster its first page w/ insignificant old threads. Another was posting grotesque pictures of people with diseases.
Sometimes we discover him when he stops using the proxies or mixes them up. Other times it's just his over-the-top rudeness, which is one reason I think of him as insensitive. The other is that "Insensitive" was one of his early usernames.
