@Cqm:

That's not a particularly good solution, what about people who want their own custom prefixes, and don't  care about specific gadgets or abusefilter, would they keep whitelisting certain prefixes for each Wikia?

Personally, I've always believed that the MediaWiki namespace is a bad solution to a serious problem. Users should never have direct access to the interface of any program. That's an inevitable source of MediaWiki security exploits.

One core principle of user interface design is that you don't assume the skillset of the user and prevent them from making obvious mistakes. The MediaWiki namespace violates that principle by assuming that an "admin" is a competent designer / programmer / internationalization expert, and not protecting them from their ignorance.

The best approach would be to simply create another namespace for this kind of thing, and/or design an interface for manipulating simple (text) messages without worrying about a namespace.
