I simply don't understand how or why people only ever have 1 email address and give it out unconditionally to anyone who asks for it. How can people live like that?
While I use these same techniques to limit spam to my email addresses, you and I are in the minority of people who have the resources, time and savvy to do this.
Without a wide-spread educational campaign I don't think it's fair to expect the average user to have the time or resources to do this, let alone even have the idea. The average user will prefer to rely on their provider supplied spam filter than mess about with 130 addresses.
Dude.. you have 130 email addresses??
