I'm not sure who you're answering or agreeing with, but my point is still
that 90% of everybody blocked has no clue whatever about what to do about
it, and esp. the people with infected systems. A standard channel *to* an
ISP for this kind of technical issue - either the ISP notifying the
spammer that their machine needs to be cleaned before they'll be allowed
back online, or between ISP, would do something useful. But I doubt very
much that most of those 90% of users who are *not* spammers, nor infected,
would have any idea to complain to their ISP that something needed to be
done, and so the ISP goes on thinking there's no problem. The result that
*I* see from that is that people simply drop, or change services, and
nothing gets fixed.
