Suppose someone implemented a list which for any IP address returned

reject") as well as for other purposes ("if the score is low but not
low enough for auto-accept, subtract 2 from the SpamAssassin score; if
it's high but not too high, add 2; if the list says the IP emits much
but not all spam, run these extra checks").
Do please pick a name. I've been working on prototype (actually two of
them) for system similar to described above ('spamness' determined based
on presense of ips in ipblock in multiple blacklists).
Many commercial firms seem to call them "reputation services". That's
a very nebulous PR name though, a better technically-descriptive name
would be welcome.
Correct and I'll just note that any blacklist or whitelist is a reputation
service.
for what it's worth, IADB is another one along those lines -- quite
long-standing at this stage.

Well, I'll not reveal the details right now (and there are still some
tough algorithm problems I'm trying to resolve on the concept I'm
working on), but let's just say that it is going to be nothing like iadb.
