Misinformation is a serious problem on YouTube, and it's starting to get people hurt. A perfect example is "Miracle Mineral Solution," a chemical tonic promoted by a healer and self-proclaimed "space bishop." According to him, this medicine can cure a variety of ailments -- including autism. But make no mistake, Miracle Mineral Solution does nothing of the sort. It's actually a completely different chemical, one that's poisonous if swallowed: bleach. Worse yet, people are actually consuming it!
