Hmmm I feel like all of these should be done at the hivemind level, It's basically a way to change the sorting/viewing algorithm, and approving posts make little sense when we could instead make the algorithm show the posts (or not) automatically.

If you haven't started working on it, if I were you I would be enclined just look at the hivemind code and implement them there, the code is pretty straightforward, but I do get that it would be much faster to just implement them at peakd's level.

How often these would change would be pretty rare I would assume.
