I use the term “assumed audience”, cribbed from Chris Krycho. For example, look at these two posts of his — one, two—with little placards up top making it clear they are aimed at different groups of readers. Those groups might overlap! They might also: not.
I like this idea! Don’t know that it would do anything to deter trolls, to combat context collapse, but this use case seems helpful of setting expectations for the piece and helping readers understand whether it’s for them before investing much time.
