I've used escrow with a few transactions with shady people, and it totally saved the transactions. Other people have done transactions with these same people, without escrow, and suffered losses. Escrow is ALWAYS a good idea, no matter who you are trading with.

They have their own decisions, but the community is advised to be careful. There are still many difficulties that need to be overcome. Especially related to finance.
