I have absolutely no advice to give on the iptables rules, but I wonder:
what do you think about something of a community database of these bad
boys (and girls)? I for one would like to ally with trustable folk like
you, blocking them off completely. I haven't begun to think of the
technology we'd need to keep in-sync with each other and handle address
additions, since I'd rather start with knowing what you (and everyone
else) thinks of the concept. :)
