> If I wander a few videos too far away I start seeing videos about reptilians controlling the world on channels with 8M subscribers and they show "footage of people shapeshifting caught on camera", completely fabricated alternative history, flat earthers uncovering the grand conspiracy of the globalist etc.

If you click on that kind of shit, of course youtube is going to show you more. I don't know how people think youtube works but it seems like it should be obvious. If you click on nonsense "ironically" just to laugh at it, youtube doesn't know that and is going to show you more. Even if you dislike and "don't recommend" the video/channel, youtube doesn't know why you disliked it. Maybe you disliked it because the video said the aliens are from Venus but you know they're actually from Alpha Centauri. Youtube doesn't know why you disliked it, all they know is that you clicked on it in the first place, so they'll try to find more to show you.

All I click on is videos about ships, airplanes and trains. That's all youtube recommends to me. No wacky shit in my recommendations because I never click on anything even remotely wacky, not even just to laugh at it. Youtube is a mirror that reflects your viewing habits back at you. If it recommends trash it's because you watch trash. Btw I don't even use an account, just a cookie.
