If I upload a post with hinata and tag her shouldnt naruto be tagged by default considering she's in the show?

We have that system. It is the implications system, more tags need to be added. gelbooru.com/index.php?page=tags&s=implications

Sometimes it does, but most times it doesn't.

It is an actual feature, funnily enough, but it only seems to work for a certain amount of tags. It's very incomplete.

Chun-Li will automatically add "Capcom" and "Street Fighter", but Tifa Lockhart doesn't add "Final Fantasy 7" and "Square Enix"

Is there a reason why we can't request implications and aliases the same way it is possible in other sites? Last time I checked the implication list there wasn't an option to request new ones

As far as I know we are only importing implications from Danbooru. Like was said, the system is incomplete. Aliases can still be requested by users. They must be approved by a member of the staff who can approve them though.

So i should have to go to danbooru and pray they approve implications? Just checked it and seems like we can request them there, but wouldn't be surprised if they had some dumb reasoning why it is fine to add implications like a new pokemon to it's own gen, but reject the idea of implications for characters to their copyrights even tho they are more important.

I will post a simple request and hope it doesn't end in a ban.

update: seems like for some reason it isn't possible for character tags to imply copyright tags, at the moment of submiting the post it simply said "Can't create implication hex_maniac_(pokemon) -> pokemon (Can't imply a character tag to a copyright tag)".

I don't care about them asking why, i simply would like to know if it is possible for us to implement them.

No. As Jedi said, it is currently impossible for us to add an implication without importing it from Danbooru, so if they aren't able to create the implication, we can't either.

......How is it impossible to implement a feature unless it's imported from Danbooru?

It isn't impossible to implement the feature. The feature is already implemented, but the only way to use it is by importing. We do not have a way to manually add an implication.
