Angelsdoll Ieseul is on topic, but the same company's Ieseul Cat Avatar [whence Janvier Jett] is off topic. The official reason given by one of the mods is "because of the aesthetics of the doll's face sculpt." I know what those words mean, but they don't make any sense because the aesthetics of the Cat Avatar's sculpt are the same as regular Ieseul's sculpt, and she's allowed.

It is a mystery.
