As a casual YouTube viewer I don’t even go based off the dislike button tbh. And if a video is being spammed with it then it’s well deserved
Be forgetting the dislike button honestly. Never thought it did much besides give angry nerds something to do about a video game or movie trailer they didn't like.
Honestly this will help game devs get away with making and selling bullshit though cause hiding the dislikes and only showing the likes will make people believe a game they made is good. Of course that's only one example of how this can be taken advantage of. I'm sure there are more, potentially negative ways this can be abused.
