I am not talking about reverting transactions, or owing something. I am talking about finding the identity of the scammer, or helping the police to find him.
... and so how do I reconcile that aspect with my company's privacy policy where I won't give out information about them without a court order instructing me to do so?
Easy, you don't give out any customer information without a court order instructing you to do so. See how easy that was?
So I came for the loony libertarian pseudo-anonymous cryptocurrency, and I stay to give out my client's information because they happened to be six degrees of separation from a scammer?
It is a common misunderstanding of Libertarianism that you get to to do whatever you want to do exactly they way you want to do it. In fact, other people also get to to do whatever they want to do to the same extent, and if that includes revealing information that you would prefer to keep private, that's tough.
