I started my first anti-spam experiment today, and it's a long-term one. I got rid of all the mailto: links on my web pages, replacing them with an image of my address and a link to a form for sending me mail. The idea is to confirm or disprove my theory about viruses targetting me due to finding my address in web cache files on infected machines. If this theory is correct then I may see a gradual drop-off in virus mail, as the old web cache files expire over the next few weeks or months.
