   <p>The simple communications blocking protocol specified herein is intended to be a user-friendly "front end" to a subset of the functionality defined by the privacy lists protocol (<cite>XEP-0016</cite>). If a service deploys both privacy lists and simple communications blocking, the service MUST use the same back-end data store for both protocols. (Note: Wherever possible, this document attempts to define a protocol that is fully consistent with <cite>XEP-0016</cite>; if a particular aspect of functionality is not specified herein, the relevant text in <cite>XEP-0016</cite> shall be taken to apply.)</p>
-  <p>A service SHOULD map the blocklist to the default privacy list, where each blocked JID is represented as a privacy list item of type "jid" and action "deny". If this is done and none of the user's clients ever use the privacy lists protocol, then the blocklist will always apply. This mapping has the following implications:</p>
