That's not a bad idea, Crazy☾. But the prep work in adding artist/UA/primary tags would also take a lot of total man-hours. It does address the problem of one person marking duplicates though.
So whenever I begin the massive tagging project (e.g., coming up with a set list of tags, tagging all of the untagged images, retagging the improperly tagged images), I'll have to incorporate those tag suggestions.
In the future, it would make finding duplicates much easier. But that also requires cooperations from image uploaders to not only tag the images, but to tag them properly. And most users here aren't going to refer to a list to see what tag should be used for a four-pane comic: "4 pane", " four pane", "four panel comic", "4-pane", "4-panel"…
That culture of image tagging hasn't been established. It isn't (and likely won't be) enforced. We lack image moderator capabilities (most moderators with image powers have entry or forum powers, meaning a lot of time is devoted elsewhere.) I don't expect enough uploaders to cooperate with tagging guidelines. It may be a pet project; "save a few starfish while the majority die on the beach" kind of thing.
It's a good idea, but it may be impractical due to our capabilities to moderate/most image uploaders.

I misunderstood you then, but I think you also misunderstand me. I accidentally lost my post when checking for ninjas, so I'll be brief.
KYM benefits by being an image repository, even though I believe the image galleries were originally meant to show off only notable or pivotal media for phenomena. KYM gets a lot of view, I'm sure, through the galleries as they are. Some end up being messy or rather vague/broad, but if image galleries like Reaction Faces only had the most notable fraction of all Reaction Faces, then it might not be as appealing to users anymore.
