How I would end SPAM
Wild ID is pretty cool. It allows you to obtain a Digital ID for free, with Wild ID acting as the certificate authority.
Now, here is my theory on how to put an end to spam. Everybody signs up for a free digital ID with one of several trusted certificate authorities. These certificates would cost exactly 1 cent each, thus forcing you to provide accurate credit card information with a name and address. Mail servers are set up to only accept e-mails that are digitally signed. That’s it.
If somebody starts spamming you, you can pull up their information from their certificate and turn them over to the spam cops.
What about people that don’t have credit cards, such as people in third world countries? Don’t they deserve to sign up for these certificates too? I didn’t say my plan was perfect.
