Interesting - so one out of every 12.5 million spam email messages actually works. I wonder what the rate is for the 419 scam

If they just had to pay 1 cent per email, the dynamics would be fundamentally changed.

How might one make that happen?

Bill Gates (among others) has already tried. http://www.cnn.com/2004/TECH/internet/03/05/spam.charge.ap/ If he failed, I would say there isn't much hope of getting it done.

Simply insist that everyone change to communicating via cell phone SMSs.

even 1 cent per 1000 emails would fix it!
