How Spam Finds You

 

Unsolicited bulk e-mail—spam—could account for as much as 70 percent of global e-mail traffic by 2007. Each day, Internet giant America Online blocks up to 2.4 billion spam e-mails from members’ mailboxes. How do spammers find their victims? Mostly through e-mail addresses posted on public Web sites (for example, when companies provide e-mail contacts for their employees). Contrary to popular online myth, little spam results from online purchases or the unauthorized sharing of e-mail addresses. This graph shows the results of a six-month study by the Center for Democracy and Technology (www.cdt.org) in which more than 250 test e-mail addresses received 8,842 spam messages.
