@hoergen Hmmm, I don't see the problem here to be honest. I don't want to explicitely add people to a particular group or forum. I just actually would like to be able to send out posts avoiding they're visible to everyone globally, either by looking at some "explore" timeline or by knowing a link to a post. I'd like to make a restriction that limits posts to be available to people I follow (or maybe mutuals of mine) without enforcing that these people necessarily have to follow each other too to reach each others posts. The latter might be perfectly valid but it seems a different use case at least to me.
