The solution for that is review by a smart person who is empowered to consider the context and use her professional judgement, not a static set of criteria.
For example, consider two smart Wikipedia editors working on the climate change and global warming pages... one from the fossil fuel sector, one from the renewable energy sector.
2) If she exists, and is as smart as she should be, she will realize quite quickly that her power can be used for personal gain and she will become corrupted. Power corrupts, etc. and you can't really entertain any kind of organizational solution without considering game theory of the situation.
