I'm assuming this has been the case all along, so I'm not sure how the accuracy of only the recent provider reviews would come into play.
Just as you likely take the "sum of the whole" in the reviews of a provider you are contemplating, so do many providers with the reviews of a prospective client. I don't have full VIP anymore but when I did that's exactly how I communicated with some of the prospective clients. One had a lot of reviews for "spinners" and how in one the girl wasn't as thin as he had imagined, so I told him I wasn't anywhere near a "spinner" and that he may be disappointed if we were to move forward. That was a very useful thing for the both of us.
If a guy has a negative review for one or two providers but the rest are good, I'm likely to see him anyhow. I'm confident in my abilities and I know I provide a very good service. As long as I feel his reviews of the ladies are fair (again, by comparing), then I have nothing to worry about.
I have a feeling inaccuracies can go both ways:
-- A client accentuates the positive and plays down the negative because he truly had a great time and wants a repeat.
-- A client is a jerk and wants to hurt the provider for not bowing to his ever whim.
Either way, it's a balancing act and that's why taking in all the reviews helps.
White/black lists only offer so much. A whitelist only says the provider will see you again. NOTHING about why, the personality, etc for ME to determine if it's a good fit for us both...and a blacklist can be very specific on why a provider won't see him again but if a guy isn't on the blacklist (which is reserved for only the worst of infractions) it doesn't help me as a provider determine if he's a good fit.
Full access to reviews is a great way for a provider to determine if we are able to meet the client's needs adequately.
You clients get to choose us based on the same criteria. We should have a fair way to size you guys up as well.
And of course, everything good has a bad side.
