there is another thread about this link seemingly Russian and upsells but no word whether the photos are real or not, or some of the photos as yes it looks like a couple are Jessi Erin but not the selfies and she looks good.
Someone who had claimed to see her said she looks like the pictures but 10 years older. I haven't seen her.
But if you check Jessy Erinn's Instagram page and scroll to the bottom just hit "load more" repeatedly and keep going - they're all there. All of them. http://instagram.com/jessyerinn
