I held out as long as I could just blocking individual accounts, but about a week ago I came to the same conclusion you did.
I suspect the entire instance is just one guy who set up a bunch of accounts on his own server.
(I just blocked a user who posted to this thread for using a homophobic epithet. Probably the same guy.)

I'm convinced the whole server is just a bunch of people who beat their wives and need a place to blow off steam when their wives arent around.
It really is a cess pool over there.
