 * `federation_reachability_timeout_days`: Timeout (in days) of each external federation target being unreachable prior to pausing federating to it.
 * `allow_relay`: Permits remote instances to subscribe to all public posts of your instance. This may increase the visibility of your instance.
 * `public`: Makes the client API in authenticated mode-only except for user-profiles. Useful for disabling the Local Timeline and The Whole Known Network. Note that there is a dependent setting restricting or allowing unauthenticated access to specific resources, see `restrict_unauthenticated` for more details.
-* `quarantined_instances`: ActivityPub instances where private (DMs, followers-only) activities will not be send.
+* `quarantined_instances`: ActivityPub instances where activities will not be sent. They can still reach there via other means, we just won't send them.
 * `allowed_post_formats`: MIME-type list of formats allowed to be posted (transformed into HTML).
 * `extended_nickname_format`: Set to `true` to use extended local nicknames format (allows underscores/dashes). This will break federation with
     older software for theses nicknames.
