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?
