Not sure why you keep picking up, but whenever I get a call from anyone, I just put it on auto-ignore on my phone and my phone doesn’t even ring anymore for those people…Honestly, I’d probably move on to “white” lists soon and just delete all emails and phone calls from numbers I don’t know.
Also, I screen all my calls so in general, I don’t waste my time or pick up anything unless it’s from a number I know…(and even then, I don’t answer a lot of times)…
Just too many scammers (like your front door) that you’re better off just ignoring all of it IMO.
