In a case like this, where it seems the purpose of two artist tags is to keep their galleries split between safe and naughty, I think it’s ok that people know both artist tags are the same person.
However, the artist draws the same OC on both accounts, which creates a problem for tagging. If I follow the standard
OC name (artist name) format, then I’d need to choose one of their usernames for the tag and use it for images from both accounts, which could count as “publicly highlighting” their existence. What do I do here?
