I received a SPAM/Phishing/Blackmail email demanding payment to a specific Bitcoin wallet.

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?
