I would like to point out that “Opt out of search indexing”, the feature you’re likely referring to, does not work perfectly. From my experiments, the user’s own pages are opted-out, but their content is federated to other servers (by design), which is then rendered on other servers without the opt-out. Or at least, where their content is part of another piece of content (eg as a reply, or as a parent post).
