|Avoiding Spam||Blocking Images||Blocking Specific Addresses|
Spam is any message or posting, regardless of its content, that is sent to multiple recipients who have not specifically requested the message.
Web sites that are not reputable, or ones that have received your permission unknowingly through their privacy policies, may sell your email address to spammers. Just as some merchants send junk mail to your house, spammers send unsolicited email with the hope that you will buy their products or services. Since sending an email message is very inexpensive, spammers can afford to send millions of them—even if only a small number of people respond by purchasing their products. They send their messages from numerous different—and often falsified—addresses, which makes them hard to track.
To help reduce the amount of spam that comes to your Yahoo! Mail account:
Never respond to unsolicited email. One response or "hit" from thousands of emails is enough for spammers to justify the practice. In addition, a response lets the spammer know that your email address is active, which makes it more valuable and opens the door to more spam.
Never send your personal information (credit card numbers, passwords, etc.) in an email. Spammers can fake the format of Yahoo! and other trusted sites. Yahoo! will never ask you to send your password or credit card information by email.
Never follow a spam email’s instructions to reply with the word "remove" or "unsubscribe" in the subject line or body of the message unless you trust the source. This is often a ploy to get you to react to the email, which lets the spammer know that your email address is valid.
Never click on a URL or web address listed within a spam email, even if the message tells you that’s how you unsubscribe. This also alerts the sender that your email address is active and can result in more spam.
Never sign up with sites that promise to remove your name from spam lists. Although some of these sites may be legitimate, most are actually address collectors. If collectors record your address, they will value it more highly because it is active.
Never open an unsolicited email unless you have blocked HTML graphics. Blocking graphics prevents spammers from being alerted when you open the message.
