Shocked to learn that Brian Dunning has done this. I've been listening to his Skeptoid podcast for years. I always pictured someone of modest or middle class means because he solicits donations to help keep the podcast going. I didn't think he was also making millions from fraud. Ironically, 'consumer frauds' is one of things he has listed on his website as a target of his skeptical inquiry.
