I'm noticing another case of blind "canon tagging" in Kemono Friends, with Shoebill and head_wings/bird_wings in particular grabbing my attention. Not every post needs the tags, especially if they look more like two-tone hair (e.g. post #2674169, post #2650305) than feathery bird wings (post #2660580, post #2637305, post #2633463). Please pay attention to the post at hand when tagging, because dilution just makes it harder to find actual head wings.

What should we do regarding personification and extra ears in Kemono Friends?

Since it was decided in topic #10067 to not tag personification on Kantai Collection posts, I'd think the same makes sense here. kemono_friends personification has a bare handful of posts, and if we don't tag canon Friends with personification, the only ones I see that would keep it are post #2019486 and post #2670945 for the Keroro Gunsou personifications.

For extra ears, there are about two pages of kemono_friends extra_ears posts. I'm not sure how many Kemono Friends posts actually show extra ears, due to stuff like kaban solo and characters whose hair hides their human ears, but if extra_ears was added to all applicable posts, Kemono Friends would probably be a pretty good percentage of the total extra_ears posts.

Yeah, if personification is part of the series premise, then leave it off. Otherwise it would flood the personification tag, which is why we took it off Kantai Collection when it was reaching critical mass.

As for extra_ears, if it shows both the human ears and the animal ears it's okay.
