FaxSpam
At a former employers we used to get a lot of FaxSpam in the days before decent e-Fax software. We would have to replace the toner cartridge every month just to be able to receive 20 or so faxes from customers & suppliers. So, we used to keep a stack of black and white diagonal striped paper beside the fax machine and anyone who spammed us got 20 pages of that sent back to them (now they get to replace their toner as well) with a final sheet telling them that if they faxed us again we would send Big John around to insert their fax machine somewhere dark and smelly. Over the next few months the FaxSpam storm declined to a light drizzle. Eventually we got a fax machine that could be whitelisted so we ONLY accepted faxes from a validated list of customers and suppliers. I think the companies initial mistake was publishing the fax number on their website.
As for the death of the fax machine, bring it on. They are an archaic PITA and need to die!
