Here are a few tips:

• Never reply to Spam or suspicious buyers' messages, even when they entice you to reply to "remove" you from their mailing lists. Often the instructions are either bogus, or a way to collect more addresses. Replying confirms to the spammers that your e-mail address is active, and you may receive even more junk mail.
• Dont flame (send a rude message) or mail bomb the spammers address. Many spammers forge e-mail addresses to hide their real identity, so you may be flaming or bombing a nonexistent account or, worse, the account of an innocent person.
• Dont buy or sell anything through unsolicited advertising by e-mail, even if the product is something you want. By buying you legitimize spam, and thus add to the problem. Moreover, many of these offers are fraudulent.
• Report the Spam to SpamCop by going to http://spamcop.net/anonsignup.shtml . You will have to register to use SpamCop, but the service is free. You can also report to your local authorities or the Internet Crime Complaint Center http://www.ic3.gov/complaint
