I support the existing rules, since pretty much all official factions provide a higher-quality experience than their unofficial counterparts. Don't get me wrong, there are a few great unofficial factions out there, but they're few and far between.
Official factions deserve their perks since any time something happens which affects overall faction diplomacy, it's up to the leaders of the official faction to take care of it. Official faction leaders have a lot of responsibility on their shoulders to keep things in order.
All in all, ditto to Snak3's post. If you don't believe that's true, please demonstrate to me an instance where an Official Faction has been replaced by an unofficial faction due to incompetency of the Official Faction. Lack of activity doesn't count since that can be a factor outside of the control of players.
Edit: The only means of recruitment for unofficial factions I support is by something along the lines of "PM me" written in the faction's info thread - which should be in the clearly designated Unofficial Faction subforum. At most.
