My preference is to list quasi-legitimate spammers as spammers or at the
very least as a "mixed" source. Companies like verticalresponse.com
et al. have no economic incentive to curb spamming unless they are
threatened with a bad reputation.
I realize this may not go over well if you have customers who use the
service or want to receive mail from it, so a light hand is required.
We maintain an (IP-based) RBL and most of these quasi-legit spammers
end up on the "mixed" list, which is as the name implies: These IPs
are shady but not bad enough to block outright, so we add a couple of
points.

David.
