For anyone who has ever viewed a great deal of the content on YouTube, it is not a surprise that the site is filled with conspiracy theorists who say and think some of the most outlandish things ever. They try to spread propaganda just to get and keep viewers and make a little cash.
There are only a few people with YouTube channels who are not trying to over-sensationalize everything. Most of the ones that have these channels are always claiming that they have solid proof of something, but they never show it, and their little shows are just full of fluff.
It's amazing what some people will do for attention, fame, money and relevance. But that's just the kind of world we live in.
