OK, I went on tineye and two of the five images I have matched with images on flickr.  I couldn't get any more information and didn't want to set up an account there because it meant opening a yahoo account.  I wasn't interested enough at this point to do that.  So here's my question.  First of all, it's clear that all five pix are of the same person.  Why would two of them be on flickr?  What's the implication?  Isn't it possible they got there because someone lifted them from the site where I originally saw them?  Enquiring minds want to know.  Horny minds, too.

Update:  Thanks, rcdpsu for the tineye tip.  It worked.  I entered several of the pix and they were first found on flickr, from which I got to the site of a pro photographer in SF who took all of them between August and Oct. of this year.  There was even a listing on her site of people who'd viewed or copied each shot but I was unable to find the "girl" in question.  I have her e-mail address but will not tell her I've found out.  I'm very sure she's not a provider and is probably just a lonely gal seeking company on line.  She actually seems like a bright, likeable person and what's to be gained by spoiling her fantasy and making her feel like shit?  I actually am grateful to her because she inspired me to write some erotica that was a really good, creative exercise.  Anyway, thanks again!

Especially if the provider has been posting for some time.  If your area has a sufficient quantity of TER reviewers, and she's still not rated, be very suspicious.  She could very well have de-listed.
