I call it the antibody effect. My favorite example is clickbait headlines like, "Five things you MUST do if you're doing this thing. You'd never guess #3!" It used to be everywhere and now it's nowhere.
AI is starting to show this effect - people stay away from em-dashes. There's that yellowish tinge and that composition which people avoid on art. Some of this is bad, but we can probably live without it.
Instead of blocking channels, trying going through your watch history and deleting anything you've watched in the past that's similar to those. YouTube heavily leans on your history for recommendations, so if it's recommending those, it's because you've watched related stuff.
My YouTube feed never recommends any of that garbage.
