The vast majority of genuine punters do not go to the bother of registering just to leave one review of one girl. They will already have seen a number of girls and will see more in the future that they will want to review. They will also likely have comments to make on the boards. My own guess is that as much as 95% of once-off reviews are fake. I think that all once-off reviews should auto-delete after 2/3 months if there is no further activity by the reviewer. Yes, we will loose some genuine reviews but you have to look at the overall benifit to the system.
