You get a call from a number with digits similar to your own, but when you pick up the phone, it’s clearly a robocall. And then, it happens again and again and again, until you stop answering calls that appear to be local.

This annoying phenomenon, which has somehow gotten even worse over the past few months, is known as caller ID spoofing. Technically, it’s already illegal, but the phone industry has turned a blind eye to these robocalls. Not anymore.
