I'm thinking that it's sort of an official site. By that, I think that it was set up by somebody officially involved here, but that it's not yet intended to officially be an active endorsed site. It could simply be a matter of reserving the name before somebody else snatches it up (unless somebody already did).

From what I've seen of fake profiles, they tend to seek recognition fairly quickly because having lots of friends tends to lend the appearance of legitimacy. A Jessica Alba fake page with 14 friends is not going to fool anybody, but a fake with thousands of friends could make a fake look real.
