What is the limit? Zhou Tong stole close to half a million dollars, but you actually took steps to make sure his privacy was protected.
Zhou Tong hasn't been proven to be guilty yet, and the
Bitcoinica people have started legal processes to pay back the BTC. If pirateat40 doesn't work toward paying back within a few months, his case will be very clear.
They're both seeming to be scams, but pirate's not been 'proven' to be a scam any more than zhou tong has 'proven' he wasn't the hacker.
