Same. I don't think I remember the last time I came across actually "FAR right propaganda" recommended by an algorithm. Could be that the author and I differ in what "far right" means.

It's actually quite easy. If you watch something and you don't want more of it, delete it from your watch history. If it's particularly bad, you can block the channel entirely. I do this a lot for obvious AI slop content. Only subscribe to channels that are worth watching. Now my YouTube feed is almost too boring -- it's only showing me stuff in a pretty narrow set of interests and channels. I see very little outrage bait, celebrity news, "influencers," or politics.

And hide "Shorts" entirely. They will reappear after a few weeks, but you can hide them again.
