True, but a real company with real people and real assets would then be taking a real risk, financially and potentially even facing jail time. Its possible of course, see MtGox, but its not equally likely to happen as with these anonymous copy/paste scams. I hope Im not implying any of these companies is somehow 100% trustworthy, no company or person ever is. You could one day run away with an escrow,  but that doesnt mean you are as likely to scam someone as, say, Dank,
