PC World begs to differ: "Ronnie Scelson, a self-described spammer who signed such a contract with PSInet, (says) that backbone providers are more than happy to do business with bulk e-mailers. 'I've signed up with the biggest 50 carriers two or three times', says Scelson ... The Louisiana-based spammer claims to send 84 million commercial e-mail messages a day over his three 45-megabit-per-second DS3 circuits. 'If you were getting $40,000 a month for each circuit', Scelson asks, 'would you want to shut me down?'" The line between permission-based or "opt-in" e-mail marketing and spam is getting thinner by the day. Some list resellers guarantee the consensual nature of their wares. According to the Direct Marketing Association's guidelines, quoted by PC World, not responding to an unsolicited e-mail amounts to "opting-in" - a marketing strategy known as "opting out". Most experts, though, strongly urge spam victims not to respond to spammers, lest their e-mail address is confirmed. But spam is crossing technological boundaries. Japan has just legislated against wireless SMS spam targeted at hapless mobile phone users. Many states in the USA as well as the European parliament have followed suit. Ideas regarding a "do not spam" list akin to the "do not call" list in telemarketing have been floated. Mobile phone users will place their phone numbers on the list to avoid receiving UCE (spam). Email subscribers enjoy the benefits of a similar list under the CAN-Spam Act of 2003. Expensive and slow connections make mobile phone spam and spim (instant messaging spam) particularly resented. Still, according to Britain's Mobile Channel, a mobile advertising company quoted by "The Economist", SMS advertising - a novelty - attracts a 10-20 percent response rate - compared to direct mail's 1-3 percent. 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.
