Forum:Disable non-Autoconfirmed users to create Category page for anti-spam?

It seems that there are too much users creating the category pages to put spamming messages, it could be difficult to discover them. Then is it possible to disable for non-Autoconfirmed users?--HayateYuki 12:54, July 30, 2010 (UTC)
 * No, it's not technically possible to block users by namespace. MediaWiki is not strictly a CMS platform. You may be able to request the TitleBlacklist extension and block commonly-created category pages from being created, though this wouldn't prevent users from adding them to pages. -- 13:00, July 30, 2010 (UTC)
