I stumbled on black_coded while browsing and it's definitely not fitting for a general tag, but I wonder if race-related lore tags for characters would be a good idea? I have definitely seen anthro characters that were clearly intended to read as black:

Though not all of the posts currently tagged black_coded should actually have such a lore tag, some of the tags seem like they weren't based on actual intent :P The lore tags would obviously only apply to characters that intentionally are meant to read as a certain race despite being anthro (typically I see this as a thing POC furries do with their fursonas).
Anyways, just something that I started wondering about the idea of because of stumbling on that tag.
