Spam
"Spam" is mass electronic mail or junk email. Because spam is so cheap and easy to create, fraudsters increasingly use it to find investors for bogus investment schemes or to spread false information about a company. Spam allows the unscrupulous to target many more potential investors than cold calling or mass mailing. Using a bulk e-mail program, spammers can send personalized messages to thousands and even millions of Internet users at a time.
