Thanks for posting the info on Raven. The only way to curb this type of thing is to get the word out on the shady women who do this. Some of these women are really bold. They will change their name and phone number often, so you have to watch out for the pictures. Most of the time they will continue to use the same pictures. There is one women currently in the Ripoff section on TER that is identified by about five different names. She's still posting on BP using yet another name and using a different phone number, but still using the same picture!!
This type of behavior is the reason that I don't do outcall. I figure it's a lot more unlikely that I'd be the victim of cash and dash if I go see the provider. I was ripped off twice a few years ago when having a provider come to me. After that, I stopped doing outcall.
