Misogyny: let's pull the car over & chat a bit:

1. NEVER give out  your credit card info to unknown people on the internet.  Even with high-end providers this is usually a cash-only business.

2. Let's pretend you're lucky enough to randomly pick an honest service.  Using your credit card leaves a paper trail right-back-to-you.  

3.   NEVER search for providers on Craig's List.  CL's erotic section is often targeted by LE.  

Try this: join a verification service like P411, then cross-check their provider list against the reviews you see on TER.  

O.K., let's get back on the highway and please be careful.  --z

cash... and ONLY the amount you've prearranged, either on your person, or in an envelope live and in-person is the ONLY way to make a transaction with a provider!

everyone has given you good advice.  Don't even think about it.  There are two reasons for someone doing this: There is a very common scan now where scammers get large numbers of cards and bill small regular amount hoping the victims will not notice. Ten thousand cards times $1.10 for a few months is worth it and most people don't even notice the small charge.  More disastrous for you is the second possibility that she (or more likely he) will sell your credit card data around and before you know there will be hundreds of thousands of dollars charged by various people in strange places.
These people should be tracked down, locked up, and forced to listen to an infomercial for a food processor continuously for ten years.

thanks guys.  i wont be a retard.
