       | Here's an interesting question -- if you receive BTC from one of
       | these addresses as payment for something, do you refuse it? You
       | know it's stolen and you might worry someone else who you might
       | pay in the future would be able to track down that it's stolen,
       | so do you ask for "clean" BTC that isn't linked to known theft?
       | 
       | I don't necessarily know the answer here. This is something that
