Here's a great example of how YouTuber bullshit can be turned into "truth" by people who blindly believe it. There's an outrage culture war YouTuber who wears a mask and secretly runs a true 100% Neo-Nazi channel on Bitchute with a similar masked character. The takes his Neo-Nazi Bitchute scripts and re-uses them on YouTube, just swapping out his Neo-Nazi hate for "women", "SJWs", "woke", etc. A couple of years ago, he made up a fake "leaked" Indy 5 plot that got spread around places like 4chan and Reddit, and people believed it to be 100% real:
To this day there are people even on this forum who believe that YouTube bullshit made up by a literal Neo-Nazi is the real plot of the movie, which has been out for more than a year at this point.
