Or the videos you watched years ago and still remember. There is more youtube video than my lifetime why the hell would i watch the same shit over and over again?

The “not interested” button is your hero. Really, just hit “not interested” on a few of the offending genre and it should get right out of there.

If you also remove them from your history - even better

Disable your viewing history. I don’t go on YouTube deep dives like I used to, but at least my suggested videos aren’t all related to some previous dive I’ve done anymore.
