Zoomer writes "Every day, millions of people receive dozens of unsolicited commercial e-mails (UCE), known popularly as 'spam.' Some users see spam as a minor annoyance, while others are so overwhelmed with spam that they are forced to switch e-mail addresses. This has led many Internet users to wonder: How did these people get my e-mail address? In the summer of 2002, CDT embarked on a project to attempt to determine the source of spam. To do so, we set up hundreds of different e-mail addresses, used them for a single purpose, and then waited six months to see what kind of mail those addresses were receiving. The results offer Internet users insights about what online behavior results in the most spam. The results also debunk some of the myths about spam."
