Posting content involving any person who is under 18 is strictly forbidden. This includes real, drawn, and fictional content.
How does this work for aged up characters? Most of the popular anime characters are under 18 even if they don't look like children. I'm thinking of popular characters like Zero Two and Marin Kitagawa. for example and just how much of the anime scene gets alienated for the rule.
Thanks for the answer and the link. This helped clear it up.
