Maybe you can teach the "less savvy folks" you know that they shouldn't answer calls from numbers they don't recognize (and also teach them not to give personal information to anyone who calls them). Then the knowledge will spread and there will eventually be fewer victims of these scams.

I think that's more productive than chasing after the scammers. Many of them operate from outside the U.S., so it would be difficult for the FCC to go after them anyway. The best way to fight them is to deprive them of victims.
