Just got a call from a new number in my rotation of annoyance.  Googling reveals it to be yet another scammer:

480-890-7901 @ 2012-10-20 12:34pm - No Caller ID Name

I suspect this may be part of the same scam organization that stuck my number in their auto-dialer seven months ago and has been harassing me ever since.  More detail and numbers that have been bombarding me with calls are listed in my posts here:
