@amsomniac the OStatus protocol really isn't built for that kind of thing. As a dev team we're trying to move away from creating any illusions of encryption or privacy on a social network that by its nature involves tons of unknown servers automatically connecting to and retrieving your posts. We can constrain who the post is "shown to" but we can't constrain who "can see" it. OStatus just isn't good for that. Your idea makes more sense for XMPP or Matrix based networks.
