Official names or fan-names?

Are fan-names allowed for a tag if a character has no official name? Example: Poorfag. I notice several recurring characters in some comics I translate have no official names, but it feels kind of generic just tagging them as "old lady" or whatever.

It's fine to make temporary chartag names, they can always be changed if an official name is ever discovered. We have a lot of these, like blonde-haired_boy_(sunaba_(nczd5875)) or blue-haired_swimmer_(gentsuki)
