Well, I can't confirm for sure but one boring weekend evening, I responded to a Casual Encounters ad on CL that ended up, as I expected asking about roses.  The top link, top pic was the pic I received.  About twenty responses later, I get her number. I google it and it sure was not her.  It was actually a girl who recently got kinda cold busted on our board.  Because I can not be for sure, I'll leave it at that.......Its a risk for sure.  Lets leave it at that and hope someone else can help with their personal experience.  

Good luck.
