Even setting your phone to auto-ignore anyone not in your contacts is infuriating... apparently my iPhone considers any number marked as Spam Risk a "known" num

Even setting your phone to auto-ignore anyone not in your contacts is infuriating... apparently my iPhone considers any number marked as Spam Risk a "known" number and allows it to ring right through. So if you're a spam caller then you're actually more likely to get me to answer the phone by spam calling enough people to get Apple(?)/AT&T(?) to mark you as a spam caller. It's craziness.
