You can just remove them from your feed permanently. It is a bit annoying, but takes a couple of seconds per video, so isn't a huge amount of time wasted compared to how much time is spent watching the videos.

Whenever I see any video in my feed I don't want to watch I just do that, and since it runs out of things then it has no choice but recommend new and different things.

Helpful if you haven't used yt for long, but I'm not gonna click through every video I've watched for the past >decade just for yt to start recommending me unwatched 5minutecrafts videos :P

How do I do that ?

I'm only aware about the "Not Interested" menu option, but I doesn't reliably remove the video from my feed. It would probably get removed for a particular viewing session, but I usually found it gets recommended again after some days.

Is there anyways to remove the video permanently ?
