I work the at the abuse department of one of the big ISPs, and I have to note that finding effective values for those four varables is sticky business from the abuse preventers' side too. We get tens of thousands of abuse complaints every single day. Even filtering out the frequent-flyer abuse miscomplainers (certain ISPs seem to have no outbound filtering -- to cope with the very large number of times when their customers seem to confuse "Report Spam" with "Move to Trash", for instance), there's still a butt-load of data to be analysed and acted on, and only a finite number of monkeys with typewriters to churn through it. At best, it's a trans-global game of whack-a-mole, suspending orgs and consumers who have never heard the word "firewall", or at least have never learned router ACL config. Add to this the potential legal and/or press minefield of being accused of wiretapping, traffic-shaping, and other nefarious deeds, and we have to tread very gently indeed around certain abuse detection and prevention issues. In short, it's a big hairy beast, and it's even scarier if you take a closer-than-normal look. Paul (not an official spokesperson, nor a policy-maker, of any ISP or similar company)
