How can views go DOWN? Someone went back in time and decided they didn't want to watch your video? What is more believable is that YT is able to control, literally, change views on videos at their whims.
Years ago there was programs that protected children. Sites would add themselves to the list and those that had this setup on their computers wouldn't be able to access this content. I forget the name. It worked. YT adding themselves to the same age checks would easily be done by setting themselves up with a system that would flag the content, and this program/setup wouldn't allow such content to be added. The parents, you know, those that protect their children ... as it should be. Would set this up on the child's computer (and any computer that children would use, like at school or libraries. The problem would be solved.
The drawback was sites that had adult content wouldn't join. A simple law and penalty would resolve that. No need for this added bullshit.
