That's just your history of what you watched, liked, disliked, etc. The problem is that the system behind it is inherently stupid. You liked Vintage Story? Here's some Minecraft! And since they're games, you likely also like OTHER GAMES! Right? So here's some Roblox and Fortnite! Our trends say those are super popular with the cool guys and you surely are a cool guy too, right?! And with that comes all the clickbait bullshit too, so I say I'm not interested in those channels and block them, so YT now thinks I dislike gaming and scrubs everything again, until I manually search & watch another video of a game because obviously it also scrubbed the ones I'm interested in. Or you watched some music videos, REPEATEDLY? Here's all the videos you previous have watched! Now you have to click, not interested, click for why, click you have watched it already, click okay. Repeat for every video you ever watched until YT gets the hint, for at least a day or two until it repeats the stupidity again.

You literally have to fight the system constantly. It's why I don't watch YT much anymore, or use private tabs now, which bring their own issue now that they also frequently block VPN IPs and ask you to log in, but that would then again muddle my watch history and consequently spam my feed with all sorts of irrelevant shit that I don't want.

The only thing that got better over the years is the video quality, like from an encoding standpoint, the content quality went way down.
