ISPs That Actively Combat SPAM?

The Llama King asks: "Like a good netizen, I do my part to report spam. But most Internet providers merely respond with a canned e-mail and it's hard to tell whether action was taken - or when. I know a lot of abuse desks are overwhelmed and spammers can get a free ride if they pick their targets carefully. Occasionally I'll get a personalized response, and even notification that a spammer's access and/or Web site has been nuked - but that's rare, and seems to be getting rarer. What ISPs are best at responding to spam complaints in a timely fashion, both in terms of killing e-mail accounts and shutting down sites that have been spamvertised?"
