If an arthritis remedy video has 11K likes, but 250K likes, that suggests there is some problem with the content of the video. Those users should be clicking "report" rather than "dislike".
If a guy in the video says "bend your foot at the ankle all the down until you hear a loud pop and feel something give", then reporting the video will do nothing. Downvoting it will inform other users that this is maybe not a good idea.
