I kinda wonder about that. Both the "semi legit" and "full on spam" calls I get just aren't credible. It's hard to imagine anyone falling for it. Or, I'll press "1" to hear their BS pitch, and go on hold forever.

It's so cheap to do, that I suspect there's an endless queue of people trying to make money, but failing. But "failing" costs them almost nothing.

So, maybe raising the cost of doing it will kill off the amateurs.
