Louie Veleski has some interesting opinions. He thinks ghosts exist and humans have never been to the moon. A resident of Melbourne, Australia, Veleski expounds on his points of view on his YouTube channel, Better Mankind, which earns him up to $5,400 a month. Conspiracy theories, it turns out, are very profitable for the YouTube-inclined entrepreneur. On his channel, Peladophobian, Ryan Silvey, 18 and also from Australia, posts videos like “School Is Illuminati” and “Donald Trump Is Vladimir Putin.” Though satirical, the videos may be lumped in with other fanatical, contrarian or esoteric posts in search results. Silvey makes more than $7,500 a month on average from advertisements that some of his 628,000 subscribers view.
