But, did you really believe that sitting behind an ISP, behind a 'basic' firewall (router), running Windows OS, with its firewall, and you would be safe if the FBIs/CIAs/NSAs of this world (USA, UK, China, etc.) want to take you down.. you stand a chance?

I assume that a more extreme step would be to notify the ISPs that serve specific IPs to cut them off. But that would break a lot of other things.
