Check how many other ladies have gabriella as the first name.  What that means is that Kaitlyn did not pay for her own ad so most likely it is an agency or bait and switch.  

For instance my url reads like this:
http://www.eros-lasvegas.com/files/us-sara65-sara2-vip.htm

Sara paid for Sara's own ad which is the best way to tell the scammers across the board.  Stay away from those and my guess is that you will find many others beginning with gabriella too.
