The Do Not Call Registry appears to be a phone bank of functional phone numbers. It's very similar, it would appear, to laws governing SPAM, as it completely legalises SPAM, and actually makes it easier to SPAM people.
I received a call from 213-550-3111, on my work cell phone. They left no message. I called back from a landline and the message said I was called to participate in a survey, but the time had expired. I researched the number and found that the call was from Los Angeles.
This number rang on my cell phone but left no message. I'm not calling back just going to block since I'm not sure whats up with this. Would hate for my number to get cloned, had that happen to a friend and it was a nightmare for her.
