> When things do reach manual review

I’ve yet to see a case of the hoi poloi get a manual review - you either are a well enough known YouTuber where they have humans dedicated to you, you know someone who works at YouTube and can intercede on your behalf, or you have to whip up a Twitter mob big enough that it hurts YouTube's image or stirs up people with contacts at YouTube.

Even then, sometimes that doesn’t work - look at the Terraria dev.

YouTube effectively has no manual review for 99.9% of people which is why its automated systems accuracy is so important.
