I will not prevent it. If you run blacklist for UTXOs you are not using bitcoin but a downgraded shitcoin version of it.
There's no blacklist in bitcoin, bitcoin is for everyone and my enemies because it's neutral money
Bitcoin was made for fighting. The fact that its legal is merely convenience. Make no mistake, the government did try to kill it. They tried going after people in its early days and were left surprised that no matter how many people they went after the thing wouldn't die. They thought they merely had to go after more and more people until finally the thing was explained to them as to how it works which is not by people.
I guess if you really want to you can pay Chainalysis to screen incoming channel opening requests.
Does your whole Lightning Node suddenly become tainted?
As soon as a random drug buyer opens a widest possible channel of 4M sat (~$1000) to you, you will be sanctioned by US Treasury and no American will be able to have business with you. Anthony Blinken himself will tweet that US will aggressively pursue criminals like you. Or maybe none of that will happen, who knows.
Just to confirm.... I would never dream of scanning incoming channel opens but that's me. I'm not a US Individual. My question is could especially US based persons (including corporations) be FORCED to do this.
