Hmm, I've never used it, but something like Silkroad worked, it did not have trust issues. To me it reads like they try to save pennies on customer support.
The differences between Silk Road and Airbnb is that the former didn't have lots of investors and techbros to pay returns to, so they could actually offer a fair escrow service and still remain profitable, where as Airbnb has to commit fraud by pitching you an "insurance" service that never actually pays out because doing so would lower or even negate the techbros' returns.
