The GodKing is the owner of the site, or its administrator, or any sysop that finally got ultimate power. He uses his authority a lot. Some people thinks this is fair (especially when the GodKing is the creator of the site, or the owner of the server) and good (because he can insure that certain guidelines stayed no disputed). Others think it is oppressive and limit the quality of participation.
To avoid becoming oppressive, the GodKing could stay away of his site if possible, be transparent in any of his decisions, and empower others whenever possible.
