I use uBlock to stop this type of shenaningans. I set filters for specific channels or "channel networks", for instance if I don't want to see any Vice related video show up in my recomendations, i.e. "Vice Fightland", "Vice bla bla bla" etc, I set a rule such as: www.youtube.com###dismissible:has-text(/Vice/) This way, any channel that has the word Vice in it will never show up to me in recommendations, be it on the main page or the sidebar. This "has-text" regex is really useful, not just on Youtube. I use it a lot, all over the internet. In your case, switch "Vice" with "react" and I believe you'll get rid of 99% of these videos showing up on your feed.
