Lately, I go on a 30-minute “Not Interested” spree on the recommendations feed when I need to weed things out. I burn everything that I know I’m never going to watch. I have 500+ subscriptions and the ratio of those with new content to trash the algorithm hands me is too damn low. So I have to set it straight some times. After this correcting action, things are noticeably better for about a month.

Another move is to right-click and open unfamiliar stuff in an incognito/privacy window. This helps keep similar material out of your feed.
