I have been a member of the community in San Francisco for over 10 years. Both websites,
http://SFLair.org and
http://thesanfranciscolair.com, are real San Francisco Lairs. I am a member of both.
Some PUA's feel that the ".com" Lair has too much commercialism, banning, and censorship. The ".org" Lair aims for the opposite. It has no commercial posts. It is more raw and real - as opposed to having a gentle atmosphere you get on Mr. Roger's show. There are pros and cons to this, of course. The PUA's selling things can't post in the ".org" Lair. They do on the ".com" site, which averages 50 posts per day. The ".org" site averages 125 posts per day and also has a Chat room. If you offend easily you won't like everything people say on the ".org" site. The Chat room is pretty cool, though, and usually has about 6 people from 7 PM to 4 AM.
Some of San Francisco's better known PUA's (G*Spot, Ben Dover, Grifter, Pepe Le PUA, JayTee) post only on the ".org" Lair. These guys are in the chat room a lot, and Ben Dover and Grifter actually closed their accounts on the ".com" site and became moderators on the ".org" site.
Don't take my word for any of this. Check out both sites. You can't see 95% of the ".com" site, however, unless you attend one of their events. For only $30 you can attend one of their events called "Social Symposiums." Also, they don't tell you this before the events, but they force you to submit to a photograph. They didn't used to, but the site's owner Craig began telling the moderators they had to do so. One of the moderators for the ".com" site, Awesome Sauce, refused to take photographs. He stopped being a moderator for the ".com" site and became a moderator for the ".org" site.
