A good solution would be to prevent non-autoconfirmed users from creating pages. However, that is not something we are able to do, and I don't know whether the Wikia staff would be fine with it. The idea would be to allow users to edit existing pages, move them, etc., but not to create them. They would be able to create them once they become autoconfirmed, which requires having 10 edits and having been on the wiki for some days. This is a very easy requirement to match, but it'll deter people who have no intention of contributing to the wiki from coming here just to create a low quality article about a non-notable group, user or place.

Of course, we need this requirement to only apply for the main, Catalog and Community namespaces.
