If I might be so presumptuous to get back to blacklisting... WHAT ARE YOU FRICKING NUTS!?
You want to destroy Bitcoin? If we blacklist some coins then how can anyone trust that their's won't be next?! If someone (gov) can come along and say "these coin were once used in a crime, maybe not by you (but maybe you) so now you have to give them up even though you earned them legitimately more recently" then that would MURDER any hope of this being a circulating currency. If there can be such thing as dirty coin no one takes the risk of transacting. I sure as sh't hope everyone starts using dark wallets and blacklisting dies a horrible death as an idea.
