I'm unaware of any evidence consistent with this version of how things work there. By all accounts, YouTube are unlenient with bans and blacklistings. Can you please cite a source?
The original comment I was replying to was speculating about how they imagined youtube worked without evidence. All I did was provide an alternate explanation. I wouldn't even go so far as to suggest it's a bad thing that social networks avoid using more aggressive classifiers, just that I'm skeptical of the "we don't have the ability" explanation.
By all account YouTube are arbitrary with bans and blockings. That's not the same as unlenient.
The standard example of the phenomenon I'm describing is from Twitter. They successfully keep nazi content out of German twitter, but not the rest of the world. That suggests that Twitter's moderation is partially constrained by their own policies, not just technical ability. I don't think this is a far fetched understanding of how any social network works.
