Will a screensaver help stop spam?

Lycos-Europe is trying a different approach at stopping spam - provide a screensaver that generates traffic on the sites that spam advertises with the intent of driving up the bandwidth costs of that site. The screensaver can be found at Make LOVE not SPAM. While the site focuses on Europe, there appears to be a download for international English and Spanish countries. The screensaver is available for Windows and Macintosh.
