I wish I had time to do this.

That aside, I've actually setup an anti-spam process for my personal address that effectively blocks all but one or two messages every couple of months. While still letting legitimate people and companies contact me easily.

All you have to do is drop your spam-infected email address, get a new address that you don't tell anyone and then run through a system like www.sneakemail.com. Then whenever an alias starts to get spammed, drop it and create a new one.

I've also got a Spamcop address in the process, which I have as my reply-to address when I want to bypass sneakemail.

These are two completely different topics. One suggests punishment for spammers, the other is just a way to ignore them.
I think the question most people ask is "Why should I HAVE to change my e-mail address constantly?"
It's not fair that the innocent should have to do that and the people harrassing them get away with it completely.

I feel I don't have the time to do what these people do either. But I bet if I added up all the time I've spent deleting spam, and implementing filters, and doing what I can to avoid spam... it would be tantamount to the time that this guy spends, and makes a difference in more than his own inbox.
