A good amount of the spam I get is from Southeast Asia - good luck going
after them

Unless I misunderstand, you don't have a static IP address, but rather a
dynamic address (that may change infrequently) within one of those IP
blocks.
So I think the pizza delivery analogy fits this perfectly.
Since the address can change, they can't very well blacklist a single
address within the block. The only viable option is to blacklist the whole
block.
If you had a static address, I would argue in your favor since they could
tell if you were spamming and punish you accordingly.
I spend a good part of my day, every day, just deleting the spam that works
its way though my email filters. Anything that lessens that is a good
thing. I am considering turning on the reverse-lookup to ensure that my
SMTP servers don't accept email from spoofed addresses, even though that
would use up precious network resources.
