My phone number somehow got listed under my mother's info. I don't know how, but they know she's in the Medicare age bracket and they know she owns a fully paid of home in a desirable neighborhood. I get roughly 5-10 calls a day about these things. That's ignoring the fake bank and Amazon calls I get.

I've also noticed answering the call makes it much more likely that you will receive more calls in the future. Even though I usually answer the call just to make them waste an hour talking to me as I pretend to be an old man who has trouble installing TeamViewer or finding my credit cards.

Some of the spam groups have even blocked my number since I've trolled them so much. But I still get calls from their system, and when I answer it says something like "You have been blocked from contacting this number. Goodbye."
