The following ad has multiple hits on all of the images in tineye.  Makes me very suspicious.  Just trying to help.

These photos are from a company selling them as "Stock." Several of these companies are from Europe, so the scammers buy them (Or probably steal them) to perform a bait and stwitch. On top of that, there is no service, period. This is a new tactic and a complete scam.

This ad was previously pulled, and now up on Eros again-these people have no shame. The pictures are of Courtney Danielle --a model from Bloomington Ill.

These girls are ripoffs, not just her, but there are similar ads on Eros of other ripoffs. Just be careful. You are right, that girl is a ripoff. Just post a 411 if you don't know, that can save you some good money. Be safe dude!
