A couple years ago, I got people returning calls I never made for about a month. They were all elderly, and my phone number was being spoofed by people claiming to be Aetna (a health insurance company). None of them knew it was possible to spoof your phone number. Some thought I was lying and that I had been leaving voicemails as a prank. I'm sure most of them would have fallen for whatever scams these people were peddling. It's fun to imagine old cranks replying to Viagra spam and forwarding chain emails, but the reality is far darker.
