SD-exotics takes ads from them and doesn't ask one way or another if they are or aren't affiliated. I beleive this is under advice from their attorney. do you guys remember naughtia? well her photo was authentic and she arrived to get it taken and to pay in cash for it escorted by a man that looked "like a big biker guy". They get aid and they don't care who the person is advertising. If they are being sold the more money the business makes the higher the price to buy it.
You will notice one thing about the ads they place...if the providers face is shown then there isn't any nudity if she is a cop. If she isn't then they steal the pic from another provider.  The moral here?....if you really are suspect and have alot of time on your hands do a google search for escorts...all locations and search within results for the characteristics of the basic description. It can take some time but i am sure a similar search technique is used by them to find ads that resemble the lady that you will end up actually seeing.

so far the tendency is to go with old ads of escorts no longer active, from other areas that don't travel, or international ones that don't advertise in this AO.
The search engine here is probably helpful to them so it is helpful to you. think like them and how they would go about it and it is pretty easy to figure out who is who and what is what....if I were them I would do a search then I would narrow it down by searching within results, find an inactive page and go to the cache and get pics if they are there. Makes them hard to find and detect by you.

P.S. I recommend the google help page as a study guide for all of us. as well as any other research how to guides out there. it will shock and surprise you just how much information is available on the internet if you don't already realize it.

Knowledge is Power
good luck guys and stay safe.
