Could Google be spidering one site and seeing another?

So I've got an entertainment portal site called BlueBlood.net and unsurprisingly it has almost always, maybe always always, ranked at the top of Google and other search engines for a search on its name i.e. either "blue blood" or blueblood as a search.

I just noticed today that it is no longer even a first page result for its own name, with kinda a good number of incoming links linking to, naturally, the site name. WTF?

So I sign up for Google Analytics, which I probably should be signed up for anyway. And Google tells me that some of the searches which pull up BlueBlood.net are "suicide girls" and "escort lingo". There is a year plus old thread on the forums where someone asks about "escort lingo" and the string "suicide girls" is actually automatically starred out in the unlikely event that someone were to type it on the site.

So how can those be the searches for BlueBlood.net and the site name (which it always ranked super high for) not be? Is there some way Google is looking at a site other than mine and indexing it instead? Anyone have any ideas what is going on? This just seems so bizarre
