At CFAR workshop all participants were real people. But they still missed an existing opportunity to abuse the system: there were rewards for winning, but no punishment for losing. So two people could agree to transfer a lot of bits from one to another, and split the price afterwards.
Not quite true. I ran the markets, and I did threaten to fearsomely glare at people who were abusing the system. (And my glare is very fearsome).
You know the drill - If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
And, while this is an accidental exception, future open threads should start on Mondays until further notice.
