Avoiding Junk Email

One of the problems Internet users encounter is unsolicited email coming into their mailbox (called junk email, or spam). You probably wouldn't mind if it happens a couple of times a month. But unfortunately, if you are not careful, you may soon get a dozen junk messages a day.

Junk email mostly comes from people with a purely commercial motive; they try to sell you something, and use the Internet equivalent of direct mail. (Spam just for fun, or for political purposes, is so rare that you probably won't ever see it.)

Lately, some spammers (but still a minority) have become more civilized; they are afraid that the public outcry against spam will cause adoption of federal anti-spam laws. While they may not do the worst offenses, they still waste your time.

In any case, most spam is still the "hard-core" spam, where law, ethics and taste play no role. You really want to avoid it. Once you get it, you should never reply to it. Spammers may tell you that you can unsubscribe by sending them an email. However, instead they just increase the amount of mail sent to you. Once the spammer knows your email address is real, he is only too happy to send you more ads (one of spammers' biggest problems is to identify valid email addresses). Even worse, the spammer may sell your validated email address to other spammers.

To avoid spam, you can use the following methods:

As you see, some safety measures cost a lot, and you may decide to pass on them. The Usenet postings and the email registration warnings are the least costly to follow, and are almost always worth that cost.

The following features will help you to identify spam when it reaches your mailbox. Even if only some of these features are present, you should assume it is spam unless for some reason you know otherwise.

One of the best resources about spam, and about its avoidance, is available at http://www.cs.ruu.nl/wais/html/na-dir/net-abuse-faq/spam-faq.html.

The latest news on the legal battles surrounding spam is at http://www.cauce.org/latest.html (many other resources at this site are also interesting).

See also http://www.cyberpromo.org/spamlinks.htm. This site originally was intended as an antidote to the King of Spam, Sanford Wallace, and his company Cyberpromotions (the real URL for that company was www.cyberpromo.com, rather than .org). However, last year the company lost several battles in court, and was closed down for good in October. More than that, Mr. Wallace himself renounced his throne and joined the ranks of the anti-spammers. If you are interested in the spam vs anti-spam war, you shouldn't miss this fascinating story, available, e.g., at http://www.news.com/News/Item/0,4,22016,00.html.
