Here is the list of the IP addresses banned on this site. I've built it mostly in the last year using different methods:
At the early times I waited for the spamemr to write their post, then I banned the email address and the IP.
The I searched the net for some antispam services and found the honeypost web site ( http://www.projecthoneypot.org ) where I can check the IP.

This list is ready to copy&paste in a .htaccess file for you own use if you've a website
