The examples you list are the few obvious, controversial types. The majority of content creators who have been getting demonetized over the past year or two do not have a single shred of "bad stuff" in their content. There are people losing their entire income because they don't fit some algorithm that has nothing to do with (properly) categorized - or reported - content.

It doesn't help that there are apologizers who spread the idea that YouTube is somehow targeting "the bad stuff", when that is a very small fraction of what is happening. Everyone focuses on the sensationalist garbage reported by the media; meanwhile all the small channels that are playing by the rules are being left out to dry.
