I would like to think those prefer QUALITY over QUANTITY . . .
At one point, I had a NO REVIEW POLICY.
Since it's against the Rules to advertise that or post it in my Ad's, I made it clear in the appointment/session.
My reasoning is/was based on being an active Provider for 10 years now and I have plenty up to date "Quality" Reviews. I have some listed on another site and I just don't feel it's necessary to be Reviewed as often.
I have felt the need to keep my activities private while I've been involved in a relationship or arrangement, out of respect for that individual.
However, now, if asked, I have allowed some recently.
