Do spam faxes actually work on anyone? My work phone number has managed to get on one such robo-spam-faxer's list somehow, and while I've learned to recognize the number on the ID panel and just ignore it if it calls during work hours and all I have to do with the "voicemails" it leaves in the wee hours is delete them, it's still rather annoying. I've just got to wonder about this as an actual tactic to produce any profit.
