	Not many.. only the big ones.  If you're going to get into denying
address space to anyone that can justify it, because of their line of work,
you're getting into a very large sticky issue, which is seperate from
spamming, which is ip assingment policy.

	The problem is that any sort of blacklist maintained by more than
one person in their spare time gets into very sticky legal issues, and should
not be touched here on nanog.
