Some criteria I would suggest for the notability of unlicensed content: If neither of those criteria are met, a user can still post their own fan material...as subpages on their user space. What do you think?
 * That it involves talent that has also been involved in licensed works, or
 * That it has gained enough notability and prominence, especially if it has accumulated its own fanbase and attracts its own fanart, fanfiction, etc.
