So, I wasn't here for most of this either, but as I understand it:
Cogsdev was one of the original sysops of the CWCwiki and a founding member of the PVCC. Cogs actively participated in the coordinated trolling of Chris during the early days of his trolling and has a huge Internet footprint because of his activity on the Wiki. As Chris became more famous, more people populated the Wiki and, by extension, the PVCC. Cogs and co became irritated by the new users and closed the door to the forum. From then on, he only made accounts on request for what he considered good wiki editors. Because the PVCC had closed, a demand for a place to talk about Chris grew and people began to have hypothetical conversation on the talk pages of the Wiki. Cogs was also furious about this, and
@champthom ended up being the person who was to open the CWCki Forums, a containment board for forum users not good enough in Cogs's eyes for the PVCC.
As the years went by, Cogsdev kept the forums closed. He is a male-to-female tranny by name alone, and lives off the British welfare system. From what I've heard, he considers himself a sex worker despite never having performed sex acts and has groceries delivered to his door as to avoid going outside. Regardless, he fell out of trolling and kept the PVCC closed with ever dwindling numbers. It became a place for a handful of very liberal sperglords to nod their heads in unison and make petty insults towards everyone they didn't like.
During this time, the CWCki Forums grew, I adopted it from Champthom over 2013, and it was rebranded in 2014 to the Kiwi Farms. We've completely dwarfed the wiki at this point. But at the start of Gamergate (or just before), Cogs tried to get Marvin to shut down the CWCki. He said it would be a funny way to piss of "cwckispergs" (which is what snobs called us before the rebrand), but his real motivation was more selfish. He is one of those uber autistic people that refuse to change their names online, a la Moleman, and while he's very invested in social justice now, googling his username turns up his profile on the CWCki -- what is widely considered by SocJus as one of the most vicious instances of patriarchal transmisogyny gangstalking in the history of the world.
So that didn't happen because Marvin isn't retarded, and Cogsdev stays cooped up at the PVCC with a group of less than 10 people jerking each other off and talking about how great socialism and social justice is.

If Cogsdev was any more transparent, he'd be a clear cut candidate for Lolcow, but he's schizophrenic and covers his ass very well, aside from his twitter account.
