What YouTube "Truthers" say most of the time
Most YouTube "Truthers" are Masons muddying the waters mixing truth (Revelation of the method) with lies intended to cause doubt in the faith of real Christian viewers.
The transvestigation community is a good example. Take the truth that there are many crypto trannies in Hollywood and the elite, mix in lies like the belief that 90% of people on earth are all trannies unaware to cause doubt and mental instability and slowly turn normal viewers into trannies.
Also with flat Earth you get similar disinfo people promoting anti-Christian Gnostic viewpoints attached to flat Earth such as the idea that they're hiding free energy/infinite land behind the ice wall.
They all have Masonic or media based usernames like "mrE3000" (Mystery Science Theater 3000), "Peter Parker/Batman", "Hans Wormhat" (from Always Sunny in Philadelphia, a show about a gang of gay Masons and someone named "Dee")....
