In my opinion you're still missing the point. The vast majority of spam is making billions for US and Multinational Corporations who are very sensitive to protesters and camera crews. Everyone is under the false assumption that spam is the sole product of guys hiding in their basements using their computers all on their own but those are the little guys. The major players in the Spam Wars are big corporations with affiliate marketing programs that encourage spam.

Sure, all of these companies have their affiliates check a box agreeing to their public anti spam policy but Almost none of these companies do anything about the problem. Why? Because these corporations are continuing to make record profits year after year.

The one thing that scares the top 1% more than anything in the world is protesters being followed around by television cameras. Everyone's efforts to date have been to go after the guys at the bottom but it's only when we go after the guys at the top that the problem (like any other ill that affects society) that the problem gets solved.

Going after the guys at the bottom is treating the symptoms rather than treating the cause. It's a tactic that never works no matter what the problem.

And debate if you like but in the end your businesses are going down the tubes because e-mail is only a few years away from becoming useless as a marketing tool. Either the industry polices itself or the industry dies.
