Spam marketing resistance.

Momo makes a point:

Spamarketing: Time for advertising green tax?

A typical view: next to mailboxes stands a waste basket full of discarded direct mailing advertising. People hate it and yet the "analog" spamming seems to be on the rise. What a waste of paper, trees, paint, etc. The way I see it - the only way to stop it is to make advertisers responsible/accountable for such a waste of natural resources. I don't know, maybe introducing the first Advertising Green Tax will help?
