I wouldn't think it benefits the model much at all; I figured it'd be ENTIRELY the idea of the site taking the pics to come up with a fake name, mostly to support an "exclusive!" claim: "So it's a deal then. We'll pay you $ X for a few galleries - and by the way, we're gonna say your name is Agnes Frankenstein and that you're from Madagascar." "Uh, fine.......I guess."
As for Michelle, I agree with what you said. I think in her best pics (which again, in my opinion, are the Mac&B and BlueF ones) she looks better than most of the Playboy centerfolds of the past several years, and even better than a few recent PMoYs. And I'm still holding out hope that she'll get lots of work from other paysites like 24 Main Street and Foxes and whatnot.
BTW, have you noticed that if you go to michellemccurry.com the domain has at least been registered, but all that's there is a blank white page?
