And from this I'm interpreting: If we block mail from the IP blocks (or all IPs from offending ISPs), then there customers will eventually get fed up with them and change ISPs.
Well, Len, this is the real world. And in this real world, those customers of the offending ISPs don't blame the ISPs...they blame the receiving mail server...us! These customers are educated by the ISPs to blame the "other guy"...us! It's all about the money. If they tell the truth, then those customers will force them to shut down spammers, but the spammers pay them money, too. A lot of money evidently, as I get spam from thousands of AOL, RR, earthlink, adelphia, etc accounts. Anyone see the conflict of interest here?? This is why the largest ISPs are on the top of the offending list, and why they are bullies to everyone else.

[This email took a suspicious route to arrive here; Suspected SPAM (4)] >>Is this becoming common practice to just deny entire IP address blocks >>due to listings on spam databases? Sure, if your MXs statistics show that 5 or 10 addresses from a Class C are abusing you, then you have every right to block the entire Class C. The network operator responsible for the Class is not policing his network, so your concluding that other IPs in that Class will sooner or later also be spamming you is valid. A good analogy is that the network operator is operating a factory that is spewig crap that is polluting your air, so you boycott all that factory's products. This is the logic behind blocking "subscriber" networks by PTR hostname and by HELO hostname. Your MX is receiving 10's of 1000's of spams from charter/att/comcast/rr/telus/pacbell/sbd/etc/etc/etc networks, for every handful, if any, of valid msgs, so you block all those subscriber networks until those multi-$$billion network factories, which huge, highly competent, highly paid IT staffs, stop polluting your email environment.
