Overview
One of the strengths of electronic communications media is that it costs virtually nothing to send a message. These media are not free of charge: setting up a cellular telephone network or an Internet e-mail service has substantial overhead costs in equipment and connectivity. However, once these costs are paid for, the cost to transmit a message to a single recipient is minuscule when compared with older media such as postal mail. Electronic messaging is cheap and fast. It is also easy to automate: computer programs can send out millions of messages via e-mail, instant message (IM), or Usenet netnews in minutes or hours at nearly no labor cost.

Spam is frequently used to advertise scams, such as the well-known advance fee fraud and password phishing. It is also often used to advertise pornography indiscriminately, even in jurisdictions where it is illegal to transmit pornographic solicitations to minor children. The methods of spammers are likewise costly -- to ISPs and the rest of the network, not to the spammers themselves. Because spamming contravenes ISP acceptable-use policies, spammers have for many years gone to some trouble to conceal the origins of their spam. E-mail, Usenet, and instant-message spam are often sent through insecure proxy servers belonging to unwilling third parties. Spammers frequently use false names, addresses, phone numbers, and other contact information to set up "disposable" accounts at various Internet service providers. In some cases, they have used falsified or stolen credit card numbers to pay for these accounts. This allows them to quickly move from one account to the next as each one is discovered and shut down by the host ISPs. Finally, the costs of spam must include the collateral costs of the struggle between spammers and the administrators and users of the media threatened by spamming.
