Repetition is key to the skit's hilarity. The actors cram the word "SPAM" into the 2.5 minute skit more than 104 times! This flood prompted Usenet readers to call unwanted newsgroup postings "spam." The name stuck.

Spammers soon focused on e-mail, and the terminology moved with them. Today, the word has come out of technical obscurity. Now, "spam" is the common term for "Unsolicited Commercial E-Mail", or "UCE."

Backstabbing Businesses -
Businesses often keep lists of their customers' e-mail addresses. This is a completely legitimate practice and, usually, nothing bad comes of it. Sometimes though, the temptation to make a quick buck is too great, and these lists are sold or rented to outside advertisers. The result? A lot of unsolicited e-mail, and a serious breach of trust.

Random Address Generation -
Computer programs called random address generators simply "guess" e-mail addresses. Over 100 million hotmail addresses exist - how hard could it be to guess some of them? Unfortunately for many unsuspecting netizens - not too hard. Many spammers also guess at "standard" addresses, like "support@yourdomain.com", "info@yourdomain.com", and "billing@yourdomain.com."

Web Spiders -
Today's most insidious list-gathering tools are web spiders. All of the major search engines spider the web, saving information about each page. Spammers use tools that also spider the web, but save any e-mail address they come across. Your personal web page lists your e-mail address? Prepare for an onslaught!

Chat Room Harvesting -
ISP's offer vastly popular chat rooms where users are known only by their screen names. Of course, spammers know that your screen name is the first part of your e-mail address. Why waste time guessing e-mail addresses when a few hours of lurking in a chat room can net a list of actively-used addresses?

The Poor Man's Bad Marketing Idea -
It didn't work for the phone companies, and it won't work for e-mail marketers. But, some spammers still keep their own friends-and-family-style e-mail lists. Compiled from the addresses of other known spammers, and people or businesses that the owner has come across in the past, these lists are still illegitimate. Why? Only you can give someone permission to send you e-mail. A friend-of-a-friend's permission won't cut it.

Also, use more than one e-mail address, and keep one "clean." Many netizens find that this technique turns the spam flood into a trickle. Use one address for only spam-safe activities like e-mailing your friends, or signing on with trustworthy businesses. Never use your clean address on the web! Get a free address to use on the web and in chat rooms.

If nothing else helps, consider changing screen names, or opening an entirely new e-mail account. When you do, you'll start with a clean, spam-free slate. This time, protect your e-mail address!

Before giving your clean e-mail address to a business, check the company out. Are sections of its user agreement dedicated to anti-spam rules? Does a privacy policy explain exactly what will be done with your address? The most considerate companies also post an anti-spam policy written in plain English, so you can be absolutely sure of what you're getting into.

The best way to avoid this situation is to have a clear understanding of what spam is: If anyone who receives your mass e-mails did not specifically ask to hear from you, then you are spamming them.

Stick with your gut. Don't buy a million addresses for $10, no matter how much the seller swears by them! If something sounds fishy, just say no. You'll save yourself a lot in the end.

Spam has a long history in both the food and e-mail sectors. This year, Hormel Foods opened a real-world museum dedicated to SPAM. While the museum does feature the Monty Python SPAM Skit, there's no word yet on an unsolicited commercial e-mail exhibit. But, if all upstanding netizens work together, Hormel's ham in a can will far outlive the Internet plague that is UCE.
