Well, we know they saw it through the aggregator because that was the link they posted. Unless the poster is somehow rewarded for sharing the link through the aggregator, it seems like a valid link. How else do you discover new sites unless you use them? If there is a line that we draw to distinguish click-bait sites from higher quality aggregators, who gets to determine where that line is?
I'm not sure how this question applies in this case, but I think it demonstrates that it isn't such a simple one to answer. I personally saw this video directly on YouTube a few days ago, but I know there are countless others I've only seen by following links.
As I reread your comment, I think I'm actually in support of your view.
