Cringely vs spam
Cringely has the ultimate solution to spam. Drumroll please..
When e-mail arrives, your e-mail client should compare each message to your address book and allow through any messages from known and accepted addresses. If a message comes from an unknown source, an automatic reply is sent saying, "I don't know who you are. If you want me to read your message, call me at 707-525-9519 and we can arrange to allow future messages to come straight through."
Great. Not only do the poor people who've had their addresses forged by the spammers as the return address get tons of mail, I have to give out my telephone number to people so that they can talk to me in person as well as send me a message online.
Go Cringe!
[edit: Is that Cringe's real phone number? I'm afraid to call it...]
