To understand the problem of spam, you really need to know who's doing all the inbox overloading and what they're advertising with their floods of e-mails. Surveying the Internet, you can quickly see
To the contrary, the most commonly mailed spams advertise pyramid schemes, get-rich-quick scams, phone-sex lines, pornographic Web sites, and quack medical products. Most ironically, vast quantities of spam advertise spamming software, spamming services, and lists of millions of e-mail addresses you can buy so that you too can become a spammer. You may even encounter spam that's out to sell you antispam filters!
Spammers actually fit into three categories of people who may be responsible for putting a particular pience of spam in your inbox:
The first category is the advertiser. You can't have spam without somebody who wants to advertise something. They may be sophisticated technical experts who do their own spamming, or they may be computer illiterates who saw an advertisement and decided to hire a third party to send spam for them. Whoever they may be, they are generally the people responsible for whatever message is contained in the body of the spam, and generally the one to whom you make out the check when it's time to buy the miracle hair-growth or body-part enlargement product.
