It does what it says, but still, nothing can fix YouTube's cancerous search results.

For example, I watched an Angry Joe Video about Blood Bowl (videogame) a few months ago. Well, if I search for "Tabletop Blood Bowl Second Season Review" I get that video I already watched from Angry Joe as the third result, which is completely irrelevant.

2 scrolls down, there's an Angry Joe video for The Last of Us, followed by an Angry Joe video from 13 years ago, Then a few relevant results here and there, and then an ocean of shitty video gaming channels I used to watch a decade ago.

It seems like YouTube's algorythm is trying incredibly hard to show you what it thinks you
"really" want instead of what you ACTUALLY asked for... but hey, at least no more stupid YouTube shorts in my results thanks to this addon.
