    This illustrates dumb idea #2. Explain to me how you intend to enumerate
    enough of the "bad" hosts out there that such a blocklist would help, while
    still having it small enough that you don't blow out the RAM on whatever
    device you're installing it on. Have you *tested* whatever iptables/ipf/ACL
    for proper operation with 10 million entries?
