“They have a private person’s name come up.”

“He’s wrong. I’ve gotten it from telemarketers collecting for mosdos.”
The “private person’s name” that the mosdos fundraisers are displaying on your caller ID is in all likelihood the caller’s actual home phone number that he’s calling you from (on behalf of the mosod.) As such it makes sense that you’d see a private person’s name. And that is above board.
