If an artist on NNS has only one very common name and nothing else to go by (no external links to their official website, Pixiv, etc. to get another name to qualify them), what should be the standard qualifier? There seems to be inconsistency on the few existing artists like that (whether there are one or two "nico"'s, whether "seiga" is included, whether the artist's ID number is in the tag, etc.)
