I just found out and find it fascinating. The way it was explained is that there two groups in two different cities in Australia. He also said he believed there were groups elsewhere like in the US.
In their group, (not the Catweasel one), one person was an IT guy who developed the software. This enabled them to first of all totally mask their identity through an additional layer and also would only allow one of the people to access or post as the avatar at a time. The way I imagine that today different people can work on a single cloud document simultaneously, like Google Docs.
All cyberpunk spy thriller stuff, and I guess they probably really got off on that aspect of it.
I believe there was some suspicion back then that the avatars were being run by multiple people simply because of the times they were posting.
He also mentioned that Catweasel was a single individual though, but also part of the other group. Apparently Catweasel has died. I didn't ask for his/her identity and didn't think it was my business.
This is all from a public FB post, so I am just repeating it here.
