If you're like me, chances are you're constantly getting bombarded by robocalls. You know the type: You pick up the phone only to hear some pre-recorded message — sometimes not even in English — about how you owe someone money or you've won a free vacation to Barbados.
These sorts of robocalls are smarter than ever, too. Spammers are capable of spoofing the area code where you live so that it appears to be a local call or even one from a legitimate business you've used. And of course you answer: Maybe it's a neighbor, the drug store or a doctor calling.
Usually it isn't.
