Is there a way to report/shutdown a Bitcoin Criminal/Bad-Actor? I received a SPAM/Phishing/Blackmail email demanding payment to a specific Bitcoin wallet.


  BTC: 15vUqauqHybEPvXYLv97WW4XwM2YHXYC1d


How can this criminal be shutdown?

If legal action is problematic, could a "User Rating/Classification" be added to BTC Wallets so that it's possible to "tag" Bitcoin users who are using this technology for illegal purposes?

Being a BitCoin criminal seems to be very lucrative.
Bitcoin is supposed to be permissionless and censorship resistant. That's the whole point. So, no, you can't do that.
