I understand where you are coming from dub1 but even if a client is not registered on the board, it doesn't mean that if the escort doesn't provide him a good service he cannot register and leave her a bad review.
Being contacted by someone registered on the board makes the booking much smoother and personaly makes me more comfortable than just answering a phone call by someone that I have not seeing before. I mean some girls use the referral system which helps a lot but not all do the same.
In many cases, people are registered on the board, but they don't write reviews, so being contacted by a member of the board is not a garantee that the escort is going to get a new review.
And answering your question, I don't think the escort is going to give a special treatment to someone only because he is a trusted reviewer, recently I saw a review from a trusted reviewer in which he said that he had contacted the lady previously via PMs but when he got there she didn't even was wearing make-up, so she knew who she was waiting for, this is just an example that I can remember now.
