I'm not sure that would help in anyway tho? I mean if the funds you received are deemed "coming from a hacked exchange" or a "terrorist organization" because they went through a mixer. I don't think that you providing those details would really help. It might even escalate things.
So you're saying there is no way to use a mixer and cash that crypto out to fiat at an exchange?
I'm not saying that. I'm talking about the scenario where your funds are blocked due to suspicious activity. Just because you used a mixer does not guarantee that your funds will be locked. But if they do lock your account,then I think that you sending the details you mentioned would do you any good.
