Fax spam? What the hell?

Ok, sitting here minding my own business, programming flash movie. Window pops up "New fax, blah, blah" Well, the boss sometimes gets random faxes, so I went and opened it and it's FAX SPAM. So, fax is not a very popular communication medium. Why the hell would you ever use it for spam? People are dumber than I thought, and that's BAD.
