Would you like to make $5,000 a month for your home? Yes or no, you are more likely to find such unsolicited offers flooding your E-mall inbox these days than ever before, along with a free trial for professional teeth whitening and a low-rate mortgage.   Such E-mail, best known by its pejorative appellation, spam, has been annoying Internet users for years. But in the last three months, Spare has been spiked.Spam-watchers attribute the escalation to a bination of factors.In a slumping economy, panies going out of business may be selling their lists of customer E-mail addresses to pay off creditors.     Mailing tactics have also improved. Online marketers have always selected addresses from Web sites, but with the growth of sites like eBay, the online auction service where thousands of people post their E-mail addresses, automated sweeps of the World Wide Web for E-mail addresses are obtaining more results.    Many now use "dictionary attacks," in which a puter automatically matches binations of thousands of mon words and names with long lists of large domain names ([email protected] corn, [email protected], corn and so on) sends E-mail messages to all of them, much like telemarketers dialing numbers in sequence. As a result, even people who have made efforts to keep their E-mail addresses private will find their mailboxes stuffed with suggestions on how to make money fast or reduce their debts simply and easily.Marketers worry that people who feel constantly assaulted by junk E-mail are less likely to trust any mercial munication by E-mails, even from businesses they might otherwise be happy to hear from, like a retailer alerting them to a sale on an item they are, interested in. To shield themselves from junk E-mail, many Internet users have bee increasingly wary of divulging their addresses.     Some mainstream marketers are already beginning to see the effects of resistance to junk E-mail. Only a year ago, advertisers were raving about the response rates to targeted E-mail, which could reach as high as 20 percent. But that number is falling fast. Still, critics say some online retailers with well-known brand names also contribute to the problem by automatically adding customers to an E-mail list unless they specifically ask to be kept off.   United Airlines, Amazon. and Martha Stewart. , among others, all require customers to uncheck the "yes" box on their Web site that asks if they would like to receive E-mail from them-or, in some cases, an unspecified list of advertising "partners" . Some times, it is not entirely clear that there is a choice involved.    The difficulty of defining Spam is one reason-efforts to pass federal legislation to stop it have foundered. Critics have pared junk E-mail to unsolicited faxes, which are illegal under a law that was passed when receiving a fax was quite expensive.1.[不定向选择题]Well-known online retailers, which contribute to the Spam problem by automatically adding customers to an E-mail list unless they specifically ask to be kept off, inluding. __________A.United Airlines B.hotmail, C.yahoo, D.excite, cor n 2.[不定向选择题]The damage done by Spam to businesses can be shown in__________A.the distrust of customers in mercial munication by E-mail B.the interest of customers in E-mails alerting themto sales.
