I have two stories -
I have stuck with my regulars lately unless I am traveling.
When traveling - I hired and did an incall. When I walked into the building I passed a twink carrying a bag of trash downstairs, and I when I got in the apartment, it was clear that the trash had been hastily taken from the room - the place was filthy. And the guys photos were obviously massively outdated.
I asked to use the bathroom and then got half the cash out, and when I came out I just said "yeah its not going to work, but thanks for seeing me - here is half the fee" and put it down and walked out. He had no reviews and I wanted to wait a few weeks before I left a review here and on RM but he has since let his add expire.
Next one - I hired a guy I had my eye on for a while. He has a pretty big following on twitter and had many good reviews here. The problem? He wouldn't send a face pic. Due to the recommendations here, I decided to hire anyway. He was prompt, clean, friendly and performed well and did everything I wanted to do. The only thing was I was really not attracted to his face and he was fully bald. Nothing wrong with being bald, I like it on some guys. But had I seen his face I really don't think I would have hired. I think this guy knows this, which is why he would not send a face pic rather than being 'extra discrete'. In this case I decided not to leave a bad review or comment here because he was a nice guy and it really was my fault for not insisting on seeing a face pic. Lesson learned.
Moral of the story - If you hire someone with no reviews and their pics are not real, be prepared to just leave some cash, in addition to a bad review, it's the risk you take.
