So if you have a problem with someone dumping crap onto your network and you've done everything you can to get the provider to stop the offender, and they won't, what would you do then? Ignore it?
Depends on the nature of the abuse. If you're blocking his packets, and he isn't jumping to a new address block, then your problem is solved. If the ISP never terminates his account, why should you care? He's already out of your hair. If his ISP gives him a new address block in order to get out from under your filters, then that's something else. Now the ISP has taken specific action in support of the spam. At this point, but not before, escalating the filters to cover the rest of the ISP's address space would make sense. -- David
