I was thinking you could hard-code in an array of "illegal" bitcoin addresses (those of the perpetrators) so that no client will invalidate Bitcoins originating from them. Also, you could hardcode in an address that starts with the amount of Bitcoins stolen, and give allinvain the private key. I'm sure it could be done though I don't know the technical specifics.
You could actually turn it into an entire component of the client where you hardcode in reversals of fradulent activity, based on democratic and fair judgements.
I'm sorry but this is an awful idea. Who is going to use a client that allows the community to vote away the bitcoins in wallets?
The legal system does the same thing... and I think it is fair. I would use it.
then use the legal system.
what you propose opens the door for chargebacks. then bitcoin would suck worse than paypal.
Yes, no chargebacks. No democratic or "fair" processes or features are needed either. It is up to the user to protect their wallet.
Also with the new planned encryption features in the bitcoin wallet (and future security features I am sure), it will be safer for the average user.
But still their responsibility in the end though...
