Community Moderation Plans

How are communities moderated or planned to be moderated? Is it just basically the founder of the community and any volunteers they accept?

My concern is that mods need to be held accountable for biased disposition of rule violations. It's been a massive problem on Reddit, and mods themselves need to be accountable to a higher mod layer.

I think this will be important to ensuring the culture does not morph into some level of extremist views.
