While the video is very creative , I dun think we should be ridiculing these users. They can be frustrating beyond belief, true, but wouldn't it be better for us to teach them not to map claim, rather than make a video showing calling out the users who do it?
I know I'd be embarrassed to see my username plain for everybody to see.
Sure, they can be difficult to talk to about it in the beginning, but it's worth it in the end, trust me. And more often then not, you have a new friend afterward!
Though it is your channel, not mine, and all I can do is merely suggest.
Overall, you have awesome editing skillz though! And great music taste, I may add, hue. I didn't know you had a youtube channel, either, so I'll be sure to give you a subby!
