I've seen a couple of very alluring providers with good website design and great prices in relation to the beauty of the pictures.  However, there is no contact information.  The provider says that she uses a verification service that requires you to provide, among other things, a credit card number as well as the three digits on the back of the card.  Here's an example:

Is it just me, or is this an incredibly obvious scam to steal from your credit card?

Read all of the site info carefully. You are getting a temporary free membership to a site, and presumably the gal's phone number, but if you don't cancel the trial membership you will be charged a recurring fee.  It's not fraud but it's also not real screening either. She is setting herself up for trouble with LE if that is the only screening she does.

Sure the picts are great & prices low to lure guys in...  but I bet no one ever gets to meet these "providers".  
These recurring charge scams are very hard to shut off.

Im in the EXACT same boat.  Same site to verify, same website...insert KissJulia where Vanessacruz is in your link if you wanna see.  What happened with your adventure?  I'm about to pull the trigger, but I am just as vexed as you are/were concerning the cc#.  I dont wanna get laid bad enough to miss a house note behind it.

Gentlemen you need to seriously WISE UP here and think with the big head for a moment... Yes, both of these ladies are seriously HOT, but am I the only one who noticed that parts of their pages are EXACTLY, and I mean EXACTLY, THE SAME?!?!? Every single letter and exclaimation point etc is in the same place!

Open these two pages in separate tabs and see what I mean!

http://vanessacruz.escort-site.com/faq.phtml

CLEARLY both of these pages were created by the same person! **This is a scam!** I repeat.. **This is a scam** Kindly sign up for VIP and find an equally lovely lady in your given area who is NOT going to comit credit card fraud!!

Take care and use some common sense...

The websites are also pulling IP numbers to determine where you are.

I live in a smallish town.  Curiously, both these girls give their incall in my town! Go figure!
