Watching the seventh season, so I might be missing something, but I feel like the only way the hidden world within スーパーナチュラル remains unnoticed is because the world is populated によって idiots.
I mean, the Winchesters have been caught on camera time and time again on the news, when a Doppleganger または Leviathan is posing as them committing murder. While the tape of the first “Ghostfacers” episode containing them is destroyed before it can be spread to the public, the Ghostfacers are shown to have mentioned them in their web series during that one episode where Zachariah makes Dean and Sam forget their lives and rediscover hunting. Not to mention the スーパーナチュラル book series that Chuck publishes. Do the ファン just miss the fact that there are a couple of serial killer brothers with the exact same names as their お気に入り characters on the loose? Hell, the 本 go up to season 3 finale. Did the ファン miss the news reel that plays out exactly like the book? Not to mention Chuck probably also mentioned the Ghostfacers entire crew によって name before they were shown on the Ghostfacers website. A スーパーナチュラル ファン (in the canon universe, obviously) could see the Ghostfacers were real people, the Winchesters are real people, and many of the characters mentioned in the books, including Agent Henriksen (who was mentioned in the newcast when Lilith destroyed the town jail holding Sam and Dean) and the people who Sam and Dean saved. Then they would 表示する them the スーパーナチュラル series, and もっと見る and もっと見る people affected によって the Winchesters rally behind this movement, and Shabang, Shaboom, the whole スーパーナチュラル world and all its knowledge falls in on itself.
