A Yahoo message:
Important! If you don't want to receive a lot of spam from
advertisers, please note the following:

Yahoo has revised its privacy policy. Your former preferences have
now been changed. You will need to reset them. Here's how.

After logging in to Yahoo, click the tab at the top of the page that
says "Account Info." Enter your password. When that page opens,
scroll to just under your listed email addresses. Then click on
"Edit Marketing Preferences."

When that page opens, you'll see that Yahoo has set each option to
YES (please send me spam). You'll need to click on each and every
option to change it to NO. Near the bottom of the page, be sure to
check NO about phone and postal delivery of advertising then
click "Save changes."
