Even if someone was really trying to create a blacklisting mechanism to be used in bitcoin, I don't think it would be possible due to the nature of the system, in a centralized system like Ripple it can be made, not in bitcoin.
Can you elucidate us on how this could be achieved?
It is possible and was discussed under the name tainting. It is similar to fiat money where you note down banknote id numbers when they were used for a robbery. You can identify the flow of every coin. So when a coin came from a scam then it could be shown.
The plan was to investigate where the owner got these coins from in order to track down the scammer.
In fact scammers would be smart and exchange somehow. The one ending with such coins would have to explain who he is or would have coins that are worth less than they are.
And yes, that is one of Hearns suggestions. It is not implemented luckily. I support the 8MB though. Only not hearn.
I know how it works, I don't think it's feasible, you will need a central authority to say which coins are tainted, if this authority is Spanish it may work for Spanish exchanges, but you can exchange those tainted coins in a Chinese exchange, wand why would they care about the guys claiming the coins were stolen in Spain?
The central authority is one of the problems, yes. Misuse is something you can see from far away already and this central authority would have a very very strong influence.
But the language barrier should not be a problem. Coins are universal and if they are stolen in a certain country should not matter. The tainting would not be a governmental institute, so all complaints could be solved centrally.
This should never ever come.
Sometimes i think hearn in fact still works for google and he worked there in fact for the nsa. Now he only works for the nsa. His ideas are simply so stupid that it is no fun.
If that is the case then someone at the nsa made a pretty stupid decision to bring the tor ddos protection
into the code. Stupid guys.
