Having done a tad bit of research, I can put out some pros and some cons:
I think it is not real. There are a lot of photos I've never seen anywhere else before -- and a few of them even appear to be candid, which would tend to be positive proof. But they're vidcaps. I doubt Yulia would make vidcaps of her own DVDs. If she wanted fans, she'd just put up any old thing. And I doubt it would be one breast shot after another.
For whatever reason, some people like to set up on fb as sexually exciting people. Busty Kelli Garner, for example, has around a half dozen "real" pages, even listing her birthdate, hometown and various current cities. Very odd. Stalker bait? Or a new form of role-play? Creeeeeepy, to me, at least.
