Let's explore that for a second. MtGox knows which accounts got double paid and knows the specific Bitcoins it paid with. Perhaps MtGox doesn't track internally which specific Bitcoins or fractions come from where, but would be able to look the double paid entries and identify which Bitcoins or fractions were sent. There should be a case for MtGox claiming exactly which Bitcoins and or fractions were stolen.
Someone might quibble if it was theft if MtGox paid it out - that making it MtGox at fault not the receipent. I know my withdrawals never saw a double payout.
Some say redlisting is bad for Bitcoin. Others, in this case myself, say no it isn't. Bad: religious can tag someone as say PAID FOR AN ABORTION and he and his Bitcoins be damned. Good: redlisting government seized Bitcoins, redlisting stolen Bitcoins.
Lets look how much was stolen, something like 6.2% of all Bitcoins in circulation which at the moment are worth roughly $458 million dollars. It's tough to spend that much money. So they are going to sell cheap.
Who can buy in January and February? Most Americans are climbing out of holiday credit card debt and if anything will be selling. Speculators will buy most. Who lost in MtGox? Those who see the banks and wealthy in their own country devaluing their currency. What happened with the April crash of 2013. A massive transfer of wealth to speculators and a general devaluation of Bitcoin. It did come back. I know it taught me a lesson. Speculators cause currency to be devalued. Currency speculating is legal. Currency speculators just aren't my favorite people.
So, who is going to shout loudest that redlisting is a bad thing. Those who paid for an abortion? No. Speculators? Yes.
I say redlist those coins and devise a way to return the stolen property in Bitcoins to MtGox.
