It shouldn’t matter if we are federated with the users/voters so long as we haven’t blocked the instance (which is unlikely, we block very few). The instance the community is hosted on is responsible for sending all content from that community to subscribers’ instances, so if we have at least one person subscribed we should see all content we haven’t actively blocked.

TBH I’m also not sure how content shows when you’ve personally blocked the user or instance rather than it being instance blocking.
