This is like when PT Barnum would take out articles in local newspapers under a false name saying that PT Barnum's traveling sideshow was too amazing for any of it to be more than a fancy parlor trick
"He has dancing whales, which must be some sort of automatons, and his world's oldest woman must just be leather stretched over gears and debtor's bones!"
The doubters would take the articles and run around saying "Look, all these fantastical attractions are fake!" and the people who heard them were like "I want to see these dancing whales"
