I have to agree with Melissa in the thread down below, although she's a wee bit direct. But, that's one of the things I love about her! 
I also greatly admire Buffalo Soldier for having the guts to post about his mistake. He's laid himself open for the benefit of the board members. So, we should really appreciate him for doing this!
Lessons Learned:
1. Research can only go so far. It helps a lot! But, in the end, it's not 100%.
2. Gauging the provider's tone on the phone can help a little, but it's no where near 100%.
3. Arriving is "Seeing is Believing." There is no substitute for this. It's 100%.
4. Walking out on a no good, thieving, fake provider: priceless.
Dudes, if you're having trouble walking out on a jerk-off, fake provider, then think about this:
You are helping that thief steal money from honest providers who are trying to survive. That makes you an accomplice. Get it?
Think about the honest providers who make $1,500 on a trip vs. the $5,000 a fake-ass provider makes. Do you think I'm kidding? It's really that drastic of a difference. Why? Because lunkheads pay up and then bitch about it. These fake thieves do not give a rat's ass about you.
Have it straight up, figured out, front-and-center in your mind! If you're going to an unknown, you MUST be mentally ready to walk or run.
Prepare:
1. Do you have a throw-away hobby phone? Christ, for $30 or less, you can use one for your "unknowns." So what if they threaten you? Throw the phone away. Wouldn't you rather lose $30 instead of being a lunkhead who pays $200?
2. You don't give your real name to an unknown. Did you guys get that? Unknowns don't use real names, why should you?
Honest-to-goodness providers like India, Melissa, Rachel, Lee, and so on are totally cool and so absolutely worthy of our honesty and respect.
Don't you think they also deserve our respect by walking out on a fake provider?
Walking out is a potentially dangerous thing because of the probability of threats of physical abuse, among other things.
Fake providers are counting on the client being so intimidated that they give them the money. That's called extortion.
Fake providers also count on clients being too embarrassed to leave.
Fake providers also rely heavily that the client will be too horny to leave.
Fake providers are, simply, dangerous.
Clients tend to be uninformed and mentally unprepared. Even the experienced clients can be taken off guard. Clients also tend to be submissive to the perceived authority of a provider: i.e., the provider has what the client wants. They "tend" to be. Definitely not everyone.
So, if you're in a situation where you know you're taking a risk on an unknown, does anyone ever think about what they will do if the provider isn't honest? Always have a way out. It's safer.
I'd say, most of the time, the client is thinking about having sex and not about having to stand up to a fake provider. The confrontation can be uncomfortably surprising, catching anyone off-guard.
I just wish we could stop the thieves from stealing from truly awesome providers.
