This may be of interest for discussion.  (I am posting links and TER IDs for reference, if anyone is interested in checking these things out.):

     KAREN (512)947 5501 searches out as Michelle (TER ID: 143937).  The pictures look very similar but with shorter hair in the latter.  Unfortunately, her one reviewer indicates that a provider very different from the pictures showed up.

  Then there is Amy 321'946'5764, whose TER search turns up a girl posting with that name (TER ID: 151294) but who happens to post exactly the same pictures as Michelle above.   Her one reviewer also complained that the provider showing up was definitely not the one in the pictures.

So, we have three names, two phone numbers, two TER IDs, and two sets of pictures probably of the same provider.

Then there is the problem I ran into of a provider using different phone numbers and different sets of pictures, which are generally either not of her or taken in such a way that there is no way to tell.  I ended up seeing the same provider twice because of the confusion and vastly inaccurate pictures.  Though she wasn’t that bad, I never would have repeated.  Because of various similarities, I highly suspect some more recent postings of being hers, as well.
