So you're suggesting that hosting companies do what? How many emails or port 25/587 connections a (day, week, hour) makes someone a spammer if there are no objections being lodged at the abuse department?
Are we supposed to do DPI on every email that a dedicated server sends out and then decide whether it's spam? My point is if a list has a problem with a /32 they could have the courtesy to contact the ISP/host prior to causing huge problems for a /24 I'm not sure what more can be done than having an abuse department staffed up and checking all published data before accepting a customer. And I'm mostly just complaining about senderbase, because they seem to be the one that really large companies reference.

I think the idea is that you're supposed to proactively monitor your systems for abuse and generally make your network inhospitable to spammers, not just reactively move the customer to a new IP address when the unpaid anti-spammers kindly let you know you've been detected. Personally I see SORBS as the canary in the coal mine. Except for the DUHL (which identifies dynamic IPs, not spamming activity) nobody serious relies on SORBS' data. So, it doesn't much hurt when they list you. But, like the canary that dies first if the air turns bad, if you're careful to watch SORBS you know when you're headed for problems which will get you listed by a real RBL.
