I accept that generally it is not worth much but;
With some work it can be useful.
First, copy the girls page URL into the Search Box on the top left of any UKP page, that will show any links to mentions on here, short of first hand experience probably the best information available.
Check for reviews on other sites.
On AW look at who has given Feedback, cross reference the punters feedback to track who he has seen. If you can discern that he has only visited Romainians at the same location, discount the Feedback as it is probably Sergei or one of his mates. If he has seen a variety of girls, look at their profiles and copy and paste their URL into the Search Box here. When you find one on here, cross reference the Feedback and see if it matches up. Now you get to know AW reviewers who may be genuine.
It can be time consuming but probably costs less that £150 an hour.
With time you'll find a few reviewers on AW who are honest punters and only use AW for Feedback. Where I am there is one guy who reviews a lot on AW and a good review for him is a winner for me. You will not find him on any of the Punting Boards using his AW name.
As I said it all takes time but if it is saving you both money and bad experiences it is worthwhile IMO.
