Do not receive is impossible 😁

I think what gets people heated up is that you can't prevent people from sending to your nsec. It probably depends on your jurisdiction in how far you are being forced into action. Imagine some troll dusts all nsecs with OFAC sanctioned sats. In the freedom fries states of america you're now eligible for no-fly list membership.

Nope, that's not how it works. If you don't send from it, it's ok.

That's how it works for pseudonymous addresses. If they have a rel name or a real IP that is tied to your name it's something different.

Not unless you spend. You are not responsible for spam you receive. And if you don't care to even look at the nsec derived address, you don't spend.

If someone sends you dust, sure. If someone sends you > $10,000 from OFAC addresses you can bet that you spend the rest of your life convincing AI that you are not a terrorist.

Nope. I've seen how the chain analysis sw works (the few big ones). It doesn't consider received utxos unless you spend. It's the same as when someone mails you 1kg of heroin. Unless they prove you ordered it, you can't be held responsible for what you did not ask for. Don't hallucinate problems that don't exist.

True for random duded. If you are a politically exposed person they (CIA) just needs to run a hit piece on you and 99% of people will not have the skills to figure out what is true. That said, I want to see what happens when people send serious amounts (1 BTC +) If you get a truckload full of heroin delivered yo your house and not just once, but every other week...

Legal protection is the collective hallucination. In every moment I can only protect what is fully controlled by me and concealed information. Everything else is up for someone to grab under the "right" (wrong) circumstances. If you attach your clear name to your npub and do not protect your IP address you have already given up a lot of protection. Relying now purely on the rule of law.

How do they view it, if you choose to spend it by sending back the full amount to the OFAC address minus the transaction fee which you have no control over?

I have not tried it (and OFAC sanctioned coins are a bit hard to come by:). But the way it usually works is that what is tainted is not an address, but a transaction history. Sanctioned->Address->Sanctioned is a closed loop. As long as you don't combine it with your other funds (by spending it together with another UTXO), it's usually fine.

i wait for the day when they start knocking on some npubs doors.
