Searchability across instances

[dorsiflexion]

Hello,
how does Mastodon make sure the searchability of stauses stays the same across instances?

I'm trying to understand Mastodon better and just stumbled upon this question. Let's say I don't want my statuses to be included in the search results, so I set:

[ ] Include public posts in search results

If I inspect my Account or any of my statuses via the API, I don't see a flag for this option. So if another instance that is not my home instance fetches any of my statuses, how do they know I don't want my statuses to be searchable?

Thanks and regards

This is a flag on your account, not on individual statuses. Each instance checks if your accounts has the indexable flag, and if yes, it will index your statuses.

Thanks. Yes, I also just noticed that servers communicate via ActivityPub, of course, and not via the Mastodon API. In the ActivityPub representation of an account, the indexable flag is present. One can check this via: curl -sH 'Accept: application/ld+json; profile="https://www.w3.org/ns/activitystreams"' "https://$INSTANCE/users/$USER".
