Surprisingly, the only mention of the cannibalism tag I could find was in reference to the Cannibal Yuyuko pool in forum #69923. It doesn't look like there has ever been any in-depth discussion about what exactly the tag is meant for.
Personally, I'd support broadening the tag to include intelligent beings eating other intelligent beings of different species. A strict reading of the current definition would prevent us from using the tag for, say, a human eating an elf, which strikes me as a bit too restrictive.
Is that really what you want though? Bear in mind that sometimes the same base creature can be intelligent or non-intelligent depending on the series, or even depending on the individual specimen within a given series - this would create the bizarre situation where an intelligent orc (or whatever) eating a human is a cannibal, but an intelligent orc eating a non-intelligent orc is not.
Likewise, cannibalism can exist within non-intelligent species and is still cannibalism regardless. Many spiders will routinely eat other spiders of the same species, for instance.
I didn't suggest adding any additional restrictions on the tag. Obviously, an animal eating another animal of the same species will always be cannibalism regardless of their intelligence. I'm just pushing for a looser interpretation of the tag that would put it more in line with how it has long been used in practice, e.g., humanoids consuming non-humanoids, like in post #2254140 or post #2641122.
post #2610592 How to tag the cloth that is being tight enough that can reflect features of the body? Also what is that chicken? Is that related to the chicken in post #3412825?
Upon further inspection it seems like those chicken like things in post #3412825 seems to be some sort of official icon or mascot in Azur Lane? anyone know how's that named?
Is there a tag for when a character's name is romanized incorrectly such as Eli's name written as Eri in post #3420665 or is that simply a typo?
I don't think they can be said as romanized incorrectly as ri can indeed be romanized as ri, just that it's not the officially recommended way for the character
age_progression? It doesn't seem to be exatly the same concept, but close.
The example image doesn't really look like age progression, though. More like a single character with various sets of equipment and costumes. Character_sheet is probably the best tag for this.
There's no matching_hair_ornament tag, should I make it or is there a better way to tag this? Do other tags apply? It's very notable that You is wearing one of Chika's hair ornaments, and a watanabe_you clover_hair_ornament search wouldn't pick it out (all the results are You with Chika, and Chika wearing the ornament)
