Hey, we don't get new providers unless we give new providers a chance.
Consider the possibility that with a little work, you can fairly easily determine the legitimacy of a new provider and set up a safe rendezvous!
Yes, reviews are important - but only one piece of the puzzle. Not to mention, TER is just one of many review boards.
I always start at TER, and check other boards as well. I'll PM reviewers (even first-time reviewers) to gauge THEIR authenticity. Obviously, pics get googled along with names, phone numbers, etc...
I will call the provider. Often, a noob provider will know another well-known provider who will vouch for them.
Kill any LE worries by scheduling an outcall to meet at a restaurant or bar in public, and then whisk her back to your hotel. LE doesn't go for that, as they like to control the environment and cannot in public and with an unknown location move.
If we're not lazy and relying solely on TER reviews, our world opens up a little bit and we are able to SAFELY and confidently find that diamond in the rough and help her to get a break in the business.
Just my 0.02 cents.
