The Direct Marketing Association has been fighting for the right of its members to spam us for a long time. Its Web site has an illuminating article entitled, \u201cTackling the Spam Issue: The DMA\u2019s answers to one of the nation\u2019s toughest questions.\u201d The document points out that spam is tarnishing all direct marketers and piously announces that \u201cwe're all losing - consumers, businesses, and, yes, even e-mail marketers.\u201dThe DMA proposes what it calls \u201cfour pillars of responsible e-mail\u201d which I quote verbatim:* honest subject lines;* accurate header information that has not been forged;* a physical street address for consumer redress; and* an opt-out mechanism that truly works and is honored.It also proposes to:* Forbid automated, surreptitious harvesting of e-mail addresses.* Define a universal opt-out technique to be incorporated into all junk e-mail.* Post a bond (at least $500 per entity) for organizations agreeing to abide by the DMA principles in case they violate the standards.* Support federal laws that would preempt state laws on spam.* Subsidize investigation and prosecution of spammers.The DMA raises my hackles because it specifically argues for an opt-out approach to spam. All of us are supposed to be happy to receive one junk e-mail message from any of the companies in the U.S. (since it deals exclusively with U.S. spammers) and just decline to receive more.There are millions of firms in the U.S. Receiving one message from each of them occasionally could fill anyone\u2019s e-mail in-basket quickly. And why does the DMA nowhere suggest a \u201cDo Not E-Mail\u201d list equivalent to the \u201cDo Not Call\u201d list? Having to opt out of thousands of individual lists strikes me as a ridiculous solution to the problem.The DMA also fails to recognize that offshore spam is growing. Spammers know that other countries are years or even decades behind Europe and the U.S. in regulating the use of Internet resources; annoy them here and they can simply move away or contract with overseas organizations to continuing sending their spam without concern.I think the fundamental problem is economic. The entire issue boils down to abuse of the commons: greedy people sending out their garbage at virtually no cost to themselves. We may someday see enraged Internet users insisting on a micro-payment per e-mail message - say, $0.001 per message - that would lead to trivial costs for consumers and normal users of the Internet but cost spammers a great deal of money. Fail to pay your bill and you can be sued successfully for fraud. ISPs could collect these fees and put them in a general fund for legal proceedings against abusers.Now _that\u2019s_ the kind of option I\u2019d like to see for spammers.
