COPPA Confusion

For example:
I put up a Plarail video and mark it as Not Made For Kids, YouTube can now gather information on all the viewers of the video and target them with Ads that should interest them. Then, if because the FTC see's it and deems it a Toy Video that interests Kids YouTube can say that the Creator is the one that marked it as Not Made For Kids. Then I think that both YouTube and the FTC can go after you.

So in conclusion:

1. I make a nice video with little trains runnig on my colorful plarail layout.
2. I don't gather any information on anyone.
3. I don't target anyone with any ads.
4. US Air Force bombs my house.
