An anonymous reader writes "A nice little old lady I know has had her number spoofed by some car warranty scammers. They're calling hundreds of potential victims per day pretending to use her phone number, and the angry ones call her back; some of them have even left death threats. She's terrified. Some well-intending anti-telemarketing folks have posted her address on the 'net as well. How can we figure out where these scammer bastards are, and what's the state of the current legislation to prevent caller ID spoofing? I called the FBI in Boston (near where she lives) and they said they can't help. She's called her phone company, but they said they can't help either. She's had the same number for over 50 years and doesn't want to change it." If the Feds can't or won't handle it, what's the best approach here?
