The thing I've noticed on both youtube and tiktok is that universally beautiful women teasing and showing skin is literally an instant subscriber. I think this is related to how men are attracted to women. It just takes a few seconds if not less to know that this woman is desirable. The ones that do well on social media have global appeal.
So if 1,000 unique male visitors saw the half-naked super hot woman, a high % would click. And once they saw how hot she was, in a few seconds later they subscribe.. then their algorithm always has her content being shown to them.
This is very different from an educational/ informational/ opinion-based or entertainment channel where the person needs to actually engage with the video, and watch it. And after they watch it, it's often the case that they don't subscribe at all.
My channel is like this.
For tiktok/youtube, they manipulate the algorithm all the time to maximize revenue. So the hot women have a superpower. They don't penalize and demonetize them because they need them. I guess it's the same for twitch.
