I wonder how fake "art" videos differ from fake news? Certainly, the "art" videos claiming that they are real is part of the cachet, but also the fake news would not be as impactful if it wasn't believable. Maybe it is just a part of life now? There is the solution to annotate fakes instead of removing them but it is not really usable right now, e.g. I can see no way to link this article from the youtube short.
