I'm curious to know what you mean by that?
As far as youtube comments being the butt-end of jokes about bad comments, I think this is just due to the fact that video is the great common denominator (and thus, the intellectual filter is very very low). Reddit's r/videos is limited to "non-political" videos for much the same reasons (and given that r/politicalvideos is... well, let's say the comment quality is not consistent.
I don't really see how this can be improved: a voting system won't filter low-effort/common denominator comments if what the majority wants is low effort comments.
Or just if the mass of low effort comments is too large. And since low effort is easy to make, the mass will be large.

And then there's the lessons of Twitch Plays Pokemon: they had to remove the ability to request multiple keypresses at once because people kept stalling (start10) for example.
