Someone has figured out how to break it. I have it enabled yet I still receive one call a week from a Chinese speaking robo caller. Everyone I know gets these calls, some daily on their cell phones. Must be a very profitable product they're selling to afford making 600 calls to reach one person who understands Mandarin.

Those calls threaten their Mandarin-speaking target that US Immigration services are going to kick them out of the country. But the scammers (who might be dressed up as immigration lawyers) will take care of the problem in exchange for a bunch of money.
