Whoever holds the most endorsements in a region becomes the regional Delegate - the nation you see at the top of the region's page. The Delegate often (always in the feeders such as The North Pacific) has access to special abilities such as access to the World Factbook Entry for the region, and the ability to eject and ban nations from the region.
The North Pacific elects our delegates here on the forum, and due to a history of "rouge delegates" who had no problems with banning nations all over the place, we've become a bit paranoid towards nations nobody knows who get LOTS of endorsements. The Security Council works to keep track of these nations, and if neccessary, authorize the Delegate to ban them so that the nation doesn't take the Delegate's seat illegally (under our laws).
Edit: Our current elected Delegate is Great Bights Mum, who is trying to take the Delegate's seat to replace our Vice Delegate, Unterwasserseestaat, who's only supposed to be there temporarily. SO until she gets securely in position, we're a bit extra paranoid.
