Is there a way of telling MW to block certain page names, e.g. to disallow new pages that match the regex "/index.php?title=/i"? If not then this seems like a worthwhile config setting to add.
You can hook a function to the 'userCan' event, and check for action 'create' (or 'move', 'edit', 'read').
