That's not a feature we need. We need to know like/dislike ratio BEFORE clicking on a video so that we can avoid clicking on it. I end up clicking on so many spam videos cause Youtube doesn't tell you that simple number. For example, looking for sports highlights right after a game usually ends up with tens of spammy results with fake titles trying to take advantage of trendy topics.

I'm sure Youtube tries to down rank such videos but in practice it's still a big problem. I understand they are trying to protect creators from bad actors but negative feedback is usually more important than positive feedback.
