I'm not entirely convinced it is. I started a exploit development/security podcast with a couple friends a few months ago, we were banned on Youtube shortly after the 4th episode for a community guidelines violation.

We appealed it and were reinstated pretty quickly (hours), which was a genuinely surprise to me given all I've heard about the Youtube system and the assumption that channels only got unbanned by being able to attract attention.

It is, and it's not just YouTube, I follow alot of "niche" channels, and the distribution of enforcement is comical.
