With that kind of number of hits, it's probably connected with something
over a T1 - that is attractive to spammers and zombie controllers.

Absolutely agree here.
>I doubt that there -is- a really useful registry of abuse addresses
Much of what I've seen in abuse reporting seems to result in a negative
reaction, rather than any action being made to correct the abuse. Korea
became a prime target when they decided to put the Internet into every
school - maybe every classroom. At least initially, they made no effort
to install things in a secure manner, and the result was rooted boxes
sending tons of spam every minute. My understanding is that Korean
business finally noted that large chunks of Korean IP space was being
blocked, and THAT was impacting their bottom lines. They were able to
get the word out, and the security improved somewhat.

I don't know this to be true - certainly anyone spending a few minutes
reading the abuse newsgroups knows about the problem, and the sure cure
of blocking Chinese IP space, but _I_ haven't seen any reduction in the
amount of abuse from there, and if anything they are happy to receive the
spammers money for "bullet-proof" hosting services.
