Since there are so many bogus ads to dig through out there, it can be so much easier if you use the TER browser plug-in.  If you don't have anyone else invading your computer, I would suggest downloading it.  I use it all the time and love it!  Very quick and easy!!  http://www.theeroticreview.com/reviews/searchOnTER.asp

Also, while I am barking out orders, there is an advertising/verification site that I love called Date-Check.  People like Nikki Avalon and Smarty are members there also.  Both the clients and providers are screened.  Girls can link to their reviews from their ads.  Clients have profiles where girls they have seen can verify them.  Plus, they have a free trial membership.  If you know somebody that is a member, they can sponsor you in for a free trial.

From their site:
Why should you use DATE-CHECK ?
Ladies, do you have problems checking references in a timely fashion? Are you tired of playing the game of phone tag?  or getting no response checking references?  

Gents, are you uncomfortable providing detailed personal information to entertainers? Ever run in to problems where the entertainer doesn't remember you from a year ago.  

DATE-CHECK's unique website addresses these problems.  References are available 24 hrs a day with a click of the mouse.  Stop chasing people around and reduce the amount calls you get for references.
