Anti-spam plan overwhelms sites

As reported earlier this week Lycos released their Make Love Not Spam screen saver which targets 'known' spam sites.

It's really a DDOS attack, and has proven too effective. Indeed now their own MLNS site isn't responding.

Whilst I hate spam and get a lot more of it than most people, I think it's a terrible idea. A DDOS uses bandwidth and we know the spammers can move on quickly and react to any changes in anti spam.

Wouldn't they be better off scanning thier users outgoing mail and stopping spam that originates from their network?
