This is why I am so careful about what I click and what signals I send to the algorithm. If you don't want to see car crashes then don't rubber neck with morbid curiosity at the first one.

I have never seen a Hitler post but if I saw one I would immediately block that user and the algorithm knows that. It doesn't show me people arguing it shows me debates and tech. Because that's what I taught it to do. It is not even hard it just requires a little discipline.

When a friend sends a link I refuse to click on it unless my VPN is on and I'm using Mullvad Browser. I don't want their taste (which is quite often look at this outrageous thing) ruining my feed.

One trick I have is if I see a video in my sidebar on YT that I don't want to taint my profile, I copy the url without going to it and open it in mpv directly. I tend to watch all my videos in mpv, but I do usually like to have them in my browser history and save them to playlists to find later as well, so I'm just skipping that part. I don't know if this method is perfect, they should still see my IP, but anecdotally I think it's been fine.
