SPAM is computer-slang for unsolicited (mostly
commercial) e-mail. Or in other words, junk e-mail.
Stupid, wastes of resources such as advertisements for solar powered flash
lights, laser-guided bayonets and the like.
If you run a business which uses "robots" to surf the
and Web sites across the globe looking for hapless mailto URLs
in order to send your silly advertisements to, then you are a generator
of SPAM and therefore should be smitten.
