This comment explains how to find the sites: http://news.ycombinator.com/item?id=1260609

Since nobody has posted the site names yet, it's EliteMeeting.com (also run under MeetingMillionaires.com)

I really have no idea why people are so afraid of them. Maybe I'm foolish, but compared to someone like Scientology, I doubt they're terribly effective at harassment.

I posted their URL on the original blog in a comment. If they contact me, I'll probably post it widely and contact the EFF. (if they'd like to try some kind of extrajudicial methods, I hope they visit me at my office, behind the 3 machine-gun-armed checkpoints)
