Here's the weird thing about this whole area. The calls that are made as robocalls are illegal. You're not allowed to call for commercial purposes with robocalls—the end. The only exceptions are for hospitals and schools and such things. The calls are illegal, but once somebody answers by pressing “2” or “1” and talks to somebody, that call only becomes fraud when you finally send the money. While the person is trying to scam you, there's no crime going on.
That's the trick. How do you make that part easy to solve and stop? The companies can't listen to the content, because they need a warrant. That's the conundrum we're facing.
