For me misinformation as a characteristic is a big umbrella, that the discretion for it depends on the measurer. Which makes it an unreliable characteristic to censor content by.

As an example of things that can follow into the misinformation umbrella parody, humour, good/bad science, good/bad journalism, misinterpretation of intent, paranormal reports, religion. It done for the greater good. People have done surgeries in their garage, I can't believe it's from lack of credible information, and that making a general policy from the exception is a sign of a bad design.
