Seriously doubt that those chicks are one person.
I only looked at a few posts and the ones I looked at are the same. It's probably another case of links getting submitted to the wrong profiles.
I don't think Petra's Gremlins check anything, just trust that all the submissions are good. If they did check, they wouldn't be creating profiles where the surname was the name of a pic-set. Adrienne Chaise Longue being the last
I think Regina was right. Whoever created a profile of her with that name must have been drunk.
