Well . . . Conspiracy theories periodically get out of control. They are a symptom of social psychosis and there is a small percentage of the human population that is bug fuck crazy.
In times of great stress that percentage goes up and a larger portion of society goes bug fuck. As the narrative of conspiracy theories is powerfully suggestive but logically worthless it appeals to those with little ability in logic or even general information.
Its far too much work to build something logical and consistent so odd pieces of narrative (often misunderstandings) get appended onto the tale. It gets bigger and bigger and becomes more complex and confused but that keeps all sorts of people busy trying to make sense out of the breadcrumbs (an old web dev redefinition for links back to where you came from). But they are nonsensical so it becomes 99 bottles of beer on the wall, take one down and . . .
Then you wake up with a bad headache and wonder what you did with your life. And that is the nature of insanity as a debilitating disease. That's the most that a percentage of people will ever do but you need to stay away from them Psychoses become a pandemic also.
