Okay... I thought I didn't know any "YouTube stars," but I'd completely forgotten until a few days ago that one of my former high school classmates has a YT channel of over 450K subscribers. He's quite a big deal. Not sure where he lives now, but yes, I did personally know him. Nice guy, too! Lost touch with him when I graduated, but he's still doing it, and doing really well! I'm happy for him!
