If Im not mistaken, youtube contentid filtering is not working as good as Google hoped it will. People find more and more backdors or workarounds for it. Google hires like thousends of editors to watch youtube content and filter out stuff. That was one big defeat of Google. The same way they fail to filter kids content.
Im yet to see a filtering mechanism for a platform like ytb that works.
It's a very tough problem, with thousands (or more) of smart people constantly trying to circumvent it every day. But I think YouTube has the upper hand at this point. You hear way more about false positives than false negatives, and every single successful circumvention I've found is barely watchable/listenable. >50% cropping, rotation, major pitch shifting, color shifting, speed changes. They're getting by, but really just barely.
I would call that a lost battle because you need like 1% of all content to break the laws similar to the ones EU recently passed to still heavily fine them.
