The idea is very good but I think that everyone should understand the difficulty that escorts living here have with easily recognisable photos. You often see on reviews "she is beautiful, she should use her own photos". She does not use her own photos because she does not want to be easily identified by criminals, police, landlord etc.. What is safer for the escort in this regard is safer for the client.
Photos conjure up an image of the girl. When I meet that girl what concerns me is what I call the "disappointment factor". This is how pleased or disappointed I am with the physical appearence of the girl compared to the image generated by the photos.This could be rated as marks out of ten, with anything over five being pleasantly surprised. I would value this system if it could be adopted as part of the review.
