there must be some operators' list somewhere.

yep.  nanog is for whining about it, not doing/saying something actually 
constructive with technical content.

unfortunately snort does not really scale to a larger provider.  and, to 
the best of my poor knowledge, good open source tools to 
black-hole/redirect botted users are not generally available. 
universities have some that are good at campus and enterprise scale.

cymru and a few security researchers responded privately to my plea for 
solid open source tool sets and refs.  knowing the folk involved, maybe 
we'll see some motion.  patience is a virtue, within limits.
