Lycos Anti-spam plan overwhelms sites (BBC)

Interesting thing I found from Slashdot. Basically, Lycos made a screen saver that (instead of helping find aliens, or further genetic research, or something cool) sends packets to the websites of spammers to try to raise their bandwidth costs. Well, it was rather popular, and the spam websites are getting shut down by what amounts to a DDoS attack. (Lycos says that they were trying to just slow down, not shut down the sites) I have mixed feeling on this. Its cool that someone's trying to target the spammers, but who gets to say what the targets are? (these guys say they were innocently attacked by the screen saver after an actual spam company linked to pictures on their website)
