I'm actually working on something recently, that instead of being a hybrid system like peerchan currently is, with mediators and validators built in as a hybrid system, will be entirely p2p at first (though posting by proxy through an HTTP interface like you can do here can also be supported). And I'm thinking to give it this subjective moderation system. Where you can delete/filter posts and blacklist certain files on your end, and also subscribe to other deletors as you see fit type of thing. I'll post more about this when it's closer to being ready. Instead of being based on a jschan fork I'tll hopefully be something more lightweight and simpler for people to get started with. I've even heard you can compile node.js code into an executable so people wouldnt have to install node on their systems first, just be a "extract and click to run" type of thing (at first, again browser version considerations can also come later on)
