Do Not Email

Why not set up something equivalent to Do Not Call to end the SpamWars?

It's a bit trickier probably: I wonder what % of spam is a result of lists of legitimate users being sold (with the users' badly-informed permission)? It would be interesting to see this process become more transparent (e.g. if you get a spam you can figure out who sold your name).
