The review system is not perfect, but it's generally a good benchmark to indicate if the escort is genuine, the girl in the photos & if she offers the services listed. If you decide to see a girl who doesn't allow reviews, you know & have accepted the risk that you might get ripped off. I know there's nothing more annoying than being ripped off, unfortunately not all girls that advertise are genuine, so do your homework before choosing to visit someone.
If you have been ripped off by someone, you could always post & ask guys to pm you for the name of the escort, if you post the escorts name in the thread, it's more than likely to be removed.
