Well, ultimately it's a question of authority. I cannot, or have no time to, validate even the simplest statements about something non-controversial, e.g. physics, but I choose to trust scientists and ignore some guy on Youtube who claims relativity is a hoax. Removing the video from youtube by the fact-checkers would be problematic anyway, however it would be fine if there was a disclaimer on it referring a specific authority in physics that has views that disagree with it.
