I like this, a clear cut set of rules of what's allowed and not allowed and honestly what's not allowed listed here are to protect the assets and integrity of the platform.
What made POB so successful at first was it was an even playing field and that if crap content was posted those people got called out or simply not voted for. Your votes one of the most powerful things.
I dislike the free downvote as even though it might not be used that often for an attack even it happening 5% of the time to attack someone simply because you don't like them or their opinions shouldn't come free. At least make that person pay for it.
Having a central figure or group of people that are watched over by the community to downvote real honest bad content is a must in order to protect the community and keep it from being derailed. In my opinion there's no place for hate speech or down right disgusting content. Those are where downvotes should be used and accounts muted IMO.
I like the outline here though and having a clear direction by the tribe leader is important. Fully decentralized Unfortantlly leads to attacking, hate, abuse and some down right rater ugly stuff that no one should have to see ever. There are also some very good things that can come from decentralization, just sadly for the most part it always leans towards the easy and negative.
