The FTC Do Not Call List exists ( donotcall.gov ), and threatens fines against violators. Problems with it (beyond the janky lowest bid government website), is that you have to report the violators phone number, and anymore these are spoofed. Also, it feels like the FTC doesn't do anything. You never hear about enforcement actions. For a while after the DNCL came out, calls stopped, but they've been ticking up recently. I keep getting calls selling me solar panels. When I asked how they got the number, they said, "we're calling every homeowner in California." Well, that's a violation.
