"If you remove enough Dislikes it is like people liked your video all along"
- George Orwell
Yea I saw they reuploaded it 2 more times actually and changed which video the Battlenet launcher linked to i.e. a fresh identical video with the likes/dislikes reset. It didn't take long for that one to get bombarded too though.
I was thinking the same, must be YouTube removing dislikes from people who are using multiple accounts to dislike the video.
I highly doubt it. Blizzard I mean. YouTube can probably do it.
