Why should they?

These videos have now be proved to directly inflict harm to some viewers in the form of being diagnostic with the wrong condition and being administrated the wrong drug. The argument could be the same for video triggering epileptic stroke, should they be allow on a video platform, accessible to children or monetized?

I find the videos distasteful, unfunny, and frankly lame, but think the harm is self inflicted and inflicted by the parents.

I think it is more similar to if a child watches a racing video, then steals the parents keys and gets in a crash, than an epileptic trigger.
