I go out of my way to select the 3-dot menu and select not only "not interested", but then go to the second step of saying "because I don't like this content". It makes zero difference. User is "not interested" in this Football video because he "doesn't like this content"? User did the same for 15 Football videos? Perhaps user just has been exposed to enough Football videos yet.
