                ActivityPub instances federate with other instances by exchanging data with them over the network.
                Exchanged data includes things like accounts, statuses, likes, boosts, and media attachments.
            </p>
            <p>
                This exchange of data is open by default but can be <strong>blocked</strong> for instances
                on specific domains via a domain block created by an instance admin.
            </p>
            <p>
                Alternatively, if this instance is running in allowlist mode, exchange of data with remote
                instances must be explicitly <strong>allowed</strong> via a domain allow entry.
            </p>
            <p>
                For more information on domain blocks, domain allows, etc, see the following pages (all links open in a new tab):
