Net identification systems - like Microsoft's Passport and the one proposed by Liberty Alliance - will make it even easier for marketers to target prospects.

The reaction to spam can be described only as mass hysteria. Reporting someone as a spammer - even when he is not - has become a favorite pastime of vengeful, self- appointed, vigilante "cyber-cops". Perfectly legitimate, opt-in, email marketing businesses and discussion forums often find themselves in one or more black lists - their reputation and business ruined.

In January 2002, CMGI-owned Yesmail was awarded a temporary restraining order against MAPS - Mail Abuse Prevention System - forbidding it to place the reputable e- mail marketer on its Real-time Blackhole list. The case was settled out of court.

Harris Interactive, a large online opinion polling company, sued not only MAPS, but ISPs who blocked its email messages when it found itself included in MAPS' Blackhole. Their CEO accused one of their competitors for the allegations that led to Harris' inclusion in the list.

Coupled with other pernicious phenomena - such as viruses, Trojans, and spyware - the very foundation of the Internet as a fun, relatively safe, mode of communication and data acquisition is at stake.

Spammers, it emerges, have their own organizations.

NOIC - the National Organization of Internet Commerce threatened to post to its Web site the e-mail addresses of millions of AOL members. AOL has aggressive anti- spamming policies. "AOL is blocking bulk email because it wants the advertising revenues for itself (by selling pop- up ads)" the president of NOIC, Damien Melle, complained to CNET.

Spam is a classic "free rider" problem. For any given individual, the cost of blocking a spammer far outweighs the benefits. It is cheaper and easier to hit the "delete" key. Individuals, therefore, prefer to let others do the job and enjoy the outcome - the public good of a spam-free Internet. They cannot be left out of the benefits of such an aftermath - public goods are, by definition, "non- excludable". Nor is a public good diminished by a growing number of "non-rival" users.

Such a situation resembles a market failure and requires government intervention through legislation and enforcement. The FTC - the US Federal Trade Commission - has taken legal action against more than 100 spammers for promoting scams and fraudulent goods and services. "Project Mailbox" is an anti-spam collaboration between American law enforcement agencies and the private sector. Non government organizations have entered the fray, as have lobbying groups, such as CAUCE - the Coalition Against Unsolicited Commercial E-mail.

But, a few recent anti-spam and anti-spyware Acts notwithstanding, Congress is curiously reluctant to enact stringent laws against spam. Reasons cited are free speech, limits on state powers to regulate commerce, avoiding unfair restrictions on trade, and the interests of small business. The courts equivocate as well. In some cases - e.g., Missouri vs. American Blast Fax - US courts found "that the provision prohibiting the sending of unsolicited advertisements is unconstitutional".
