I don't know the answer in your case, but in my case the answer is my
employer. More specifically, my employer pays me to block junk and let good
traffic* through; that mandate does not include "block networks that we have
no reason to believe are junk in hopes of inflicting enough collateral
damage to force the spammers' upstream to clean up its act."

If your customers/employer/whomever understand they may miss data they
wanted to receive in order to help you put pressure on
lazy/abusive/incompetent ISPs, and they're okay with that, more power to
'em. I think probably more people are in my boat-- I can't afford to launch
a crusade, I just have to keep the bits flowing.

*On the other hand, in a corporate network "good traffic" can be more
strictly defined; for example I block most of APNIC, half of RIPE, most of
LACNIC and all of AFRINIC not because I think they're all spammy but because
we get no legitimate business traffic from those regions which makes their
signal-to-noise ratio effectively 0:infinite. So if you know a provider will
never** send you legit messages, go ahead and block. Otherwise,

**My sweeping xenoemailphobia has blocked 4 legit messages (3 of which were
personal non-work-related messages) in the past 6 years, and since my reject
message gives a workaround to reach me all 4 reached their intended
recipient. Compared to the 5-15k messages blocked per day over that span,
close enough to never for me-- and more importantly, for my boss.
