My usual pattern is to scroll down the page and read reviews by trusted Reviewers first (I wont be able to do this any more of course), then I look at reviews by people I know and trust. Then I'll pick a random one or two others, including a bad review (if there are any). I tend not to pay much attention to reviewers with only one or two reviews to their name. I tend to focus on those with ten or more reviews written. A bad review from a member who has written a lot of reviews will tend to put me off, even if a girl has a number of good reviews.
Overall, I have found the review system most helpful and I am one of the minority who found the trusted Reviewer badge useful when selecting an escort.
