+It's common to see artists credited with added honorifics, especially in Japanese (e.g. "-san"/"さん", "-sama"/"様").
+
+These honorifics should not be added as the artist name on VocaDB, unless the artist uses those themselves, such as:
+
+- [外道さん (Gedou-san)](https://vocadb.net/Ar/1823)
+- [P丸様。 (P-Maru-sama.)](https://vocadb.net/Ar/139823)
+- [Mr.Hedgehog](https://vocadb.net/Ar/81441)
+- [Mr. Unknown](https://vocadb.net/Ar/49412)
+- [Mrs. Pumpkin](https://vocadb.net/Ar/55077)
+
+Note that, while this rule applies when creating/editing artist entries, you should also consider this when adding artist credits so that you can find the existing artist entry (by excluding the honorifics).
+
+## Examples
+
+The following are real-world examples found on video descriptions:
+
+- Use [ポテいも (Poteimo)](https://vocadb.net/Ar/10074), not "ポテいもさん" ("Pote imo-san") (as seen on [this video](https://www.nicovideo.jp/watch/sm21177055) of [Cryogenic](https://vocadb.net/S/32102))
+- Use [redjuice], not "redjuiceさんが" ("redjuice-san") (as seen on [this video](http://www.nicovideo.jp/watch/sm4141643) of [Last Night, Good Night](https://vocadb.net/S/2443)).
+- Use [かごめP (Kagome)](https://vocadb.net/Ar/112), not "かごめP様" ("KagomeP-sama") (as seen on [this video](https://www.nicovideo.jp/watch/sm15875228) of [Absolutenote](https://vocadb.net/S/8971)).
+- Use [シエル＊ (Ciel\*)](https://vocadb.net/Ar/2320), not "シエル＊様" ("Ciel\*-sama") (as seen on this entry and [this video](https://www.nicovideo.jp/watch/sm15875228) of [Absolutenote](https://vocadb.net/S/8971)).
