It definitely is! Anyone who thinks that KLS can't act has never seen her work the room. People were actually talking about giving her money at the festival where her table got ripped off.
Well, her acting style is a sort of endearing "earnestness", like you've caught her off guard at a vulnerable moment. I would guess that if you have that ability, you use it for purposes other than professional acting. Con men probably work that ability very hard... and you wouldn't necessarily know you're being fake. It's just your way of getting along with people...
