I think she has appeared before under Billy/Bobbi.  Do a search on this name with area code 312 (or the full # of agence) and there is 1 review by dogbone which is not good.  If you search under the # of the agency 312-944-9985 you will find a few reviews of the girls and they are all pretty poor except one.

I am impressed by the picture of Nariah from this agency but am suspicious because of all the poor reviews - I am tired of wasting $$$$ when there are many other well reviewed providers.
