I just got a junk phone call, a recording, on a phone number that's been on the Do Not Call registry for a nice long time. I tried to go to the "File a Complaint" page of donotcall. gov and found:
National Do Not Call Registry
Due to the Government shutdown, we are unable to offer this website service at this time. We will resume normal operations when the government is funded.
Debido al cierre del gobierno no podemos ofrecer este servicio telefónico en este momento. Nosotros reanudaremos el funcionamiento normal cuando el gobierno este fianciado.
The call came from 727-286-2475. It seems to be notorious for garbage phone calls.
Spam phone calls are hardly the worst thing likely to proliferate while a lot of the government is shut down. But they just might be a widespread mild irritation that will convince voters that we can't leave the Tea Party in charge.
