Name and location is at least something to go on, provided it can be independently verified.
More silliness, billyjoe. Name and location are completely irrelevant to how they conduct their business.
In fact, I prefer an anonymous organization for security reasons and think a .onion site is more appropriate (Silk Road has probably the best escrow service at the moment).
the relevant question is if he is trusted by someone or something that I trust.
...now that could make sense if you have a decent idea of what makes someone trustworthy (and it has nothing to do with them releasing their ID).
Again, look for a good track record. Thieves/scammers aren't gonna go through the trouble doing good business and establishing a record just to torpedo it later.
