SovietRussia
SoRu is someone I used to regularly talk to on IRC. He is the greatest internet troll I have ever seen. From talking to this guy he was pretty smart but give that man an internet forum with a topical subject and he would perfectly emulate the most annoying 14 year old, post a new thread talking about some completely unrelated subject, and have exactly the right key words in the right places to turn the forum into a giant ball of rage.

For reference the forum was set up to get information relating to this:

en.wikipedia.org/wiki/Murder_of_Jessica_Lunsford

This is the only screenshot that managed to survive a hard drive crash I had a few years after I took it. I don't have anything of the apoplectic rage he caused remaining.

4chan in 2004/2005 was a forum that was much less well known than it is today. It was just a 15 year old Christopher "Moot" Poole's hobby site that some people from SomethingAwful knew about. It had a population consisting of some kind of strange mix of anime nerds, like me, and random paedos wanting to access the lolicon board that they used to have before Moot realised that having that on an internet forum is a really dumb idea when you are nearing prison age, and removed it and its admin. Even then, the almost rule-less random forum /b/ was a training ground college/university age internet trolls posting the most disgusting things they could find.

Moot, once decided to add to his forum and /b/ was getting a little unmanageable, and create a new forum board called /z/ and have it moderated by a different person every day, and see what happened. Unfortunately the first person he chose to moderate it was SovietRussia.

In less than a day he had not only turned it into a place that made the infamous /b/ look like mumsnet on 98% cocoa prozac, then completely covered the background in seizure inducing GIfs but he then got other people to start taking over the other boards on the forum and posting the worst stuff imaginable. /z/ was closed down, never reopened, and I'm sure the remaining staff and users from that time will never forget the day SoRu trolled the entirety of 4chan.

I swear the guy was some kind of mentally disturbed evil genius. He is probably sitting right now at a computer in the dark wearing only a gas mask and green pipe cleaners taped to his head, causing people to tear their hair out while telling them he accidentally shat in his rice krispies.

SovietRussia lives on
sovietrussia.org/ but be warned it is more headache inducing than 4chan but very funny.
