The federal government has a Web site where you can report all those Internet scam e-mails you get every day. Not that it will do any good, but maybe you’ll feel better after complaining. Here’s the explanation from the Internet Crime Complaint Center:
The Internet Crime Complaint Center (IC3) is a partnership between the Federal Bureau of Investigation (FBI), the National White Collar Crime Center (NW3C), and the Bureau of Justice Assistance (BJA).
IC3’s mission is to serve as a vehicle to receive, develop, and refer criminal complaints regarding the rapidly expanding arena of cyber crime. The IC3 gives the victims of cyber crime a convenient and easy-to-use reporting mechanism that alerts authorities of suspected criminal or civil violations. For law enforcement and regulatory agencies at the federal, state, local and international level, IC3 provides a central referral mechanism for complaints involving Internet related crimes.
The site does have a good section on Internet crime prevention that is well worth reading.
