I have heard of at least one provider that assigns a single IPv6 (/128) to each machine, and uses a single /64 for their entire server farm (possibly a different /64 for each location). The simplest solution is blacklist them until they are forced to gain clue points. Might not be realistic for some people, but if you don't cut them off from the Internet, how will they learn? The stupid, it burns. -- My main job is trying to come up with new and innovative and effective ways to reject even more mail. I'm up to about 97% now.
