YouTube engagement metrics (views, likes, dislikes, and subscriptions) reflect how many times a video or channel has been interacted with. These metrics can be an important measure of your video or channel’s overall popularity.
We want to make sure that your metrics are high quality and come from actual humans and not computer programs. It takes our systems some time to figure out which views, likes, dislikes, and subscriptions are legitimate.
Youtube literally states:
Too many dislikes?
Must be Russian robots!
