2. When backing up your claim that x structure tends to be content that prohibits insults, you Must stay objective in your definition of "prohibiting insults". You also need to somehow label many policies (prohibits insults y/n, prohibits neutral displeasing y/n, etc) or find such a dataset. Labeling that is a massive task because you can probably hardly remain objective, unless you come up with a thorough labeling system that is accepted.

3. Same thing kinda for vagueness; that is probably a badly defined metric of language and would need a strong logical definition (in terms of NLP grammar, at least).

Building off what OpKiller said, computationally (read: procedurally) this task is currently unsolved.

But humans can do this, albeit inconsistently, because we are exceptionally good at building heuristics on-the-fly. So I don't think it's not worth discussing, but a lot of the answers you'll find for specific cases is "because that's just how it is".
