AUP Enforcement is the RIGHT way to eliminate spammers. I have also worked at a large ISP, and this is one of the best ways to fight spammers. Keep making it costly and more trouble for them than it is worth. Spamhaus is far and above the most reliable RBL in the world today and does more to help in the fight against spam than any other organization I know of. They are VERY reliable in only listing sites and domains with proper justification, and even more important deal with proper cleanup and removal of listings that have been remediated in a timely fashion.
The reason you hear all the complaints about RBL's is because they are so effective. Yes, there is the occasional person that gets burnt because of their space being adjacent to spammers, but this also helps ISP's keep pressure on their clients to stay clean to prevent such over blockage.
I'm personally familiar with one client of a large ISP that had a hard time kicking a known spammer off of their network due to a long pre-existing contractual obligation, that was able to finally disco them due to Go-Daddy's listing and blocking of dozens of their domains last year. Great job Go-Daddy! Keep it up, us regular users love to see you support your AUP!
