Apparently our building elevators have a communication system that can be dialed from outside, and since they are, well, elevators, they automatically pick up the call. Now some spammers have the elevator number and the elevators being robodialed with offers for timeshare vacations that can't be disconnected by the riders.

@fobo you know, back in high school I was once asked of the best way to secure a computer from viruses and malware.
my answer of "Don't connect it to the internet" was deemed incorrect.
Shit like this makes me all the more assured that my answer was the right one.
