In Ep18, Scott Mayar talks about his encounters with the Hatman.  He's seen this entity on more than one occasion.  He hasn't spoken about his encounter with many people, and I am honoured he has chosen to share this with us.  Scott is also co-host of a great podcast called Cappan and the Meerekat, where they talk about games on various platforms.  You can check out his podcast here https://anchor.fm/CappanAndMeerkat.
