YouTube seeks ways to prevent abuse of the dislike buttonNews
YouTube is concerned about a red hot button issue revolving around, well, the dislike button on the YouTube app. This is actually the thumbs down button found under the title of the video.
The “dislike mobs” usually pound away at the thumbs down button for reasons that have nothing to do with the actual content of the video; these mobs might not like the person or company that created a video, or want a positive review of a game or phone to be overlooked by YouTube viewers. Right now, video creators can go into preferences and disable the thumbs up and thumbs down ratings, but Leung says that other options are “lightly being discussed” by YouTube.
Some options being considered would require someone downvoting a video to check a box that gives the reason why they decided to do this. There is also talk that YouTube might remove the thumbs down button completely.
