Tried to reach this hot latina escort but could email her only. Response was to call her to setup something but I needed an EscortPin to reach her. Tried to call the number she provided anyway and sure enough it required a pin to connect my call.

This EscortPin website says it is free screening but you need to provide them a credit card number to which they will charge $1 and it will disappear after a day. I found some feedback from a Google search that said once they get your CC number they continue to charge you $20 a month. The only way to stop it is to cancel the card.

Anyone have any experience with this site?

legit ladies and agencies don't need your cc #, do yourself and move on.  I don't think anyone on this board has ever advised you give out your cc # for any thing like this.

Many girls without phone numbers advertise and then they ask you to go and fill in your credit card number before you get their phone ... don't .. scam scam scam.

The number is growing on Backpage. Maybe around 10 ads are like this in my area.

The picts probably arean't even her...  if it is a FM.   Legit providers do not require a CC number.  This is a CASH business.   NEVER give out a CC #.  
That said there are a few legit screening outfits...  but they are not provider specific.  They are an optional convenience, not a requirement.
