This doesn't surprise me. Websites and blogs and search results are polluted with trash. On the plus side, it has ruined any "explore" type watching of anything for me, which is making me spend less time on these platforms.
Looking for advice? One approach that might be interesting to try is to subscribe to channels and restrict yourself to your subscriptions. You could even bookmark the subscriptions tab in Youtube so that you don't land on the main page with recommendations.
