specifically:

- cross sections of the community can be moderated if viewed from the perspective of moderated relays that host content from that community

- in this model noone can stop you from posting to a community. the community would exist as notes spread across different relays. there could be a canonical relay list associated with the community, but there could be forked or hidden parts of the community on unofficial relays. these are just different views of the community associated with the sha2 id of the community.
