I despise junk mail and last night I decided to surrender to my emotions. I built an emotional app that retaliates against junk mail. It is a usable experiment in appealing to people's emotions and using an API for real world interaction.
Introducting F Junk Mail! - http://fjunkmail.com/. It sends real world postcards to junk mail senders. Currently, it has Charter listed. More companies/addresses are on the way, but you can also enter your own address in.
I can't see a way for the offending company to fix the problem. A little formality and the recipient email address on the card would add function to fun. Something like "please remove name@example.com from all of your mailing lists. All means anything you are associated with. Remove means I never want to see your emails again. "
It is a good thought. For now people can do that by changing the text of the message. I didn't want to require people to enter their private information.
