Okay yeah that's right I have noticed that. However, even if you don't like the video, as far as I understand, it's not reason to downvote. So if it's really bad, troll, hate, spam etc, is it too much to ask to pop in the comments and downvote?

I could see this backfiring if more spam accounts pop up, but if downvoting requires some effort and an account is being downvoted quite a bit, it should be flagged for admin review.
