Death penalty for spammers?

If someone lives for 90 years, that's about 47 million minutes.

If a spammer sends out about 90 million emails and each one wastes half a minute of someone's life, then essentially they waste an entire lifetime due to their activities.

Now, you may say that 90 million emails is unrealistic, but a techradar report says that a spammer needs to send over 12 million to get a single response, so to get eight responses they incur one wasted lifetime... it would seem likely that they would want to a lot more responses than that.

On top of that there are people and organisations whose entire lives are spent combatting spam, people such as Postini, AMBX and MessageLabs, doing their best to block spam in a King-Canute-like demonstration that it's spam is a nearly overwhelming tide of junk-mail traffic.

Surely this madness has to end? I can only think it will when we have the death penalty for professional spammers as a proper deterrent!
