There are Review sites that allow that and I agree I would like to see something like that here.  Not even so much for the occasional provider feeling they need to defend something said but even to allow them to say a simple thanks for the visit or hey I had a good time too. To me that legitimizes the review and not just something he made up to get his free VIP access. Not only for the hobbiest but also for the Provider if she looks up a certain TER member reads his reviews and sees a number of the other ladies say something nice about the visits it probably means he is a good client and she would see him again. We have the white list here but honestly it never really gets used.
