I've encountered some anti-spammers who would do half- assed investigations, declare an ISP guilty, then spread the word on private mailing lists shared by all sorts of hackers, who are apparently looking for an excuse to have fun and feel good about it.
Despite our policy of not allowing spams from our network, we were labeled spammer friendly not too long ago and a minor break-in happened the same night. Just speculating, too.

Tell me about it. In the course of today's activities, I learned that one of our users with a small commercial web site on one of our servers spammed the net from an account on another ISP. The spam contained a pointer to his URL on our server. Some of the mail seems to be holding us partially culpable for the spam. I'm happy to report that the other ISP is taking action against the spam complaint, but I don't know of any interpretation of Netiquette that condemns commercial WWW sites. I don't know that I'd favor an abuse policy that encompasses WWW sites, even if they are listed elsewhere in spam mailings, but if there's a reasonable policy out there that contemplates this type of situation, I'd love to know how it reads.
