I have had some great luck on this site and I know they try to make sure everyone is legit. It is the only site that I am aware of that take this kind of effort.  I have never had a rip off  on checking the gals on this site. Of course you should be careful regardless.

Of course there are going to be some rip offs and other types of girls here. For the most part if you stay with well reviewed ladies you will not have a problem.

A reviewed lady could be LE. Possible scenario:

Guy gets busted.
In exchange for for a lesser sentence, he agrees to cooperate.
LE sets up a phony website for a lady cop.
Guy submits a phony review for the lady.

That's one reason why you want lots of reviews from guys who have done lots of reviews.

About the worst problem I find, even with some who write alot of reviews, some tend to make it out to be better than it really was.
