Just having 50-100 people in some 3rd world shithole operating 50-100 phones each with browsers that aren't logged in. Done, you now don't have flagged accounts, and you do juusssst enough human action to appear as a low attention human viewer instead of as a botfarm.
All anti-bot detection systems are only as good as the human oversight that's overseeing them, and it appears that Google and YouTube have no human oversight on this, otherwise the culls wouldn't have gotten as bad as they did before they unflagged everyone once.
