Michael Pahre reports getting a robo-call from some company asking if he knew the whereabouts of some lost cat in his neighborhood:
... How much does this service cost? A lot! Prices range from $65 for 250 robo-calls (suitable for a low-density rural location) to $425 for 5000 robo-calls in a dense, urban environment.
Note that the organization's website claims that they are exempt from the National Do Not Call Registry, which would explain why their call went through to my house despite having registered my phone number with the list.
