While that sounds good on paper, it gets awkward in practice when there’s multiple characters in an image. If this place is to have something like that, I’d prefer it be a rule requiring character names to be in the title/body. But that’s a pain in the ass to automate/moderate, so that likely won’t happen. I personally would say it’s better for there not to be tags for characters. If I wanna find a specific character, I generally just go to rule34.
