don't know exactly what the niki upsellers are, except you can see the same url hints in other profiles in other cities.  see http://www.eros-denver.com/files/se-niki19-jill2.htm for example in Denver.  similar url.  similar girl and ad.

i note that if you search miranda's phone number, you get a number that matches "chrissy" who's a ripoff also claiming incall in the u district.
