4chan, overall, might be silly, but /b/ is trolling elevated to an art form. absolutely, the most depraved and nihilistic of all the internet, so much so that it becomes something beautiful. /b/ is the works of Marquis De Sade, John Waters, Roger Corman, Banksy, Cortney Love and Dead Kennedys all rolled into one. (also, throw in Kant and Hegel for good measure, because /b/ operates under its own dialectic.)
It's the low points of humanity pursued with ecclesiastical rigor. /b/ will fuck you over in every possible way, for no reason, and you will get up whipping your bloody nose knowing you have made someone else's lulz possible. And what pleasure!
I think Xoxohth/Autoadmit (a law school admissions forum that is actually about 20 trolls using 800 user names to "flame" each other) is more artsy than /b/, though it doesn't have quite as much force. XO has resulted in lawsuits, and it has also brought to trolling the "heroic women" and "guys at my high school" memes, the WGWAG acronym, whokebe and the word "pwnsive" (a corruption of "pensive").
