Guard your email address
Before you register at a website or before you buy online, check out the company's privacy policy. Make sure it has a policy against selling your personal information, including your e-mail address.
Remove personal information from web service directories. Your email address and other personal information may be accessible from the numerous "people-finding" search and directory services available on the Web. Choose the name-removal option (if available) to remove your name, e-mail address, and other information from the directories provided by these sites
Open a second Internet account for chat rooms, public posting, subscriptions, and buying online. Some Internet providers will allow you a second email address. Use one address for these public activities, and a second private address for e-mailing friends and business associates. This tactic will allow you to keep spam out of the e-mail account you use for communications.
Fight back against spammers
Register a complaint. Most Internet providers also offer email addresses to report junk email complaints. Forward the entire "spam" message to your provider. It may have a procedure for filtering, or "mail blocking" unsolicited email.
Don't reply to the spammer! Most "spammers" not only will ignore your request to be dropped from the mailing list, but they also will interpret your response as a positive sign that the message was actually read. Don't encourage spammers by buying their products or responding to their email.
Consider using a junk e-mail filtering program. Filtering programs can block email from a specific list of addresses, or they will only accept email from a list of users you specify. Some Internet providers have filtering programs already built in to their email service.
Be aware of people finders
Vast amounts of information about consumers is available through "people finders" or "look up services." These companies use computerized databases to collect and distribute personal identifying information about consumers. The information is used to locate, identify, and verify the identity of individuals.
This personal identifying information comes from public information sources, such as phone books or public records, as well as non-public sources, such as credit headers. A credit header is the personal identifying information on a consumer's credit report. It consists of a consumer's name, name variations, address, former addresses, telephone number, date of birth and social security number. The sale of credit header information is legal and unrestricted.
Many of these services provide you with the right to "opt out" or request that they not distribute some of the information these "look up services" make available for distribution. Check with each service or company directly for details.
