Hoaxbusters, a service of the Computer Incident Advisory Capability (CIAC) of the U.S. Department of Energy. “In addition to describing hoaxes and chain letters found on the Internet, we will discuss how to recognize hoaxes, what to do about them, and some of the
history of hoaxes on the Internet.

Users are requested to please not spread chain letters and hoaxes by sending copies to everyone you know. Sending a copy of a cute message to one or two
friends is not a problem but sending an unconfirmed warning or plea to everyone you know with the request that they also send it to everyone they know
simply adds to the clutter already filling our mailboxes.” […but you knew that already, right?]
