This only proves the point to remove the dislikes as clearly those are coordinated dislike attacks. The subject matter in that video doesn't even have anything worth liking or disliking; it was pretty standard stuff. The screenshot you show has the person shown disliking it - whomever took the screenshot has an agenda. And that Twitter account speaks for itself.

Any proof of that? I really can't see how google would be vulnerable to bots and brigading. I mean, you can't use vpns or tor on google apps without solving annoying puzzles.
