I agree that the fallout from spam (false positives especially) is
reaching unacceptable levels. Don't be so quick to condemn those who
have been burned by insufficient filtering who have resorted to stronger
measures. Just because you don't need them (on the scale of your own
personal inbox) doesn't mean they're useless.

There is plenty of collateral
damage from IP blocking, but the cause of those blocks is usually ISP
supported spam.

Baloney. I receive practically no email from anyone using an ISP that
supports spam.

How would you even know? And besides, I said "collateral damage". I'm
including the case where small ISPs have IP blocks that are near known
spammers and overzealous blackhole list admins hit them too.

Do you really believe that Ben or his ISP at rrcnet.org have blocked the
optonline.net domain as a spamming network legitimately?

That's a loaded question, you just spent the rest of your message ranting
about how the blocks are never legitimate. The server in question is
listed on 4 out of 31 blackhole lists at the moment. The policies of
at least a few of those require that actual spam come from the actual
server to one of their traps. I wouldn't use them at blacklists because
I find their policies too extreme. But then again I only process tens of
thousands of junk email messages a day, probably a few orders of magnitude
below a medium sized ISP.
