hah, I called this months ago https://news.ycombinator.com/item?id=31476551 https://news.ycombinator.com/item?id=31476551 "As a simple police matter. we can track the flow of bitcoin very easily. Imagine we created a law, one is not allowed to interact with any "blacklisted/tainted" account/wallet and any account/wallet that interacts with a blacklisted/tainted account/walletn after its been marked as blacklisted/tainted is automatically blacklisted/tainted itself (easy to determine in bitcoin). I'd hazard to say, that such a policy would have a quick impact on bitcoin's valuation. now, at first glance, this type of law might seem reasonable - if an account has been marked as doing illegal actions, any account that interacts with it is benefiting from said illegal actions. However, this would setup a world of griefers. In bitcoin (I believe) you don't really have the ability to accept or reject transfers. if someone transfers coins to my wallet's address, it will be mine. Imagine someone who gains access to a blacklisted wallet and just transfers tiny amounts to all the addresses that contain massive sums of bitcoin, thereby tainting it all. "
