Aye. I fucked up once and clicked a link to a PragerU vid that was being discussed on reddit. Non-stop recommendations about OWNING LIBS for a few weeks.

It's gotten to the point where I don't click links simply because I don't want to get spammed.

At least on desktop, you can remove videos from your watch history, which I think will drop them from the recommendations algorithm. Search here and click the X on the offending videos: https://www.youtube.com/feed/history

I have gotten similar behavior but for a more innocuous subject lately my youtube feed has been flooded with Warhammer40k videos after I made the mistake of clicking on a video on the subject.

I clicked on one of his videos like a year back to try to figure out what all the hubbub was about. I have auto delete history after 3 months on. Only video I ever clicked on about him, I still occasionally get inundated with his videos every once in awhile. I can also confirm that using YouTube in this way does not lead to a lot of variety, even though I am subscribed to a large amount of things. The video recommendations do not seem to ever show me when people I'm subscribed to post videos.

It also works in the reverse, you click one video but ignore the rest and it doesn't suggest you more. Meaning that one video doesn't usually throw it entirely out of whack.

> even though I'm completely uninterested in the guy

You are so not interested in him that you a) know his name and b) watch his videos?

If you want to get rid of something you only clicked once, click something you like 2-3 times and it will not be listed in the first results anymore. After some time it will disappear if you really do not watch this kind of content.

This works with and without account.
