I'm not saying it doesn't exist. It does. Wikia's model means incompetence, nepotism, lording, spiting, griefing and probably all other forms thrive. And plenty of cases, people who come here are a victim. But... investigating all cases in order to weed out the genuine ones is an impossible task.

The point is, these cases are not straightforward. Power is laid in the community - if they want the admin out, staff will intervene. It's a somewhat libertarian approach that seems popular on the internet, but the alternative would be total control by a group of high and mighty staffers. There's no sensible middle ground. Is it perfect? Nope. But they stick to it.
