8.7.  Duties of a Moderator

   A Moderator receives news articles by email, decides whether to
   accept them and, if so, either injects them into the news stream or
   forwards them to further moderators.

   Articles will be received by the moderator either encapsulated as an
   object of Content-Type application/news-transmission (or possibly
   encapsulated but without an explicit Content-Type-header), or else
   directly as an email already containing all the headers appropriate
   for a Netnews article (see 8.2.2).  Moderators SHOULD be prepared to
   accept articles in either format.

   A moderator processes an article, as submitted to any newsgroup that
   he moderates, as follows:

   1. He decides, on the basis of whatever moderation policy applies to
      his group, whether to accept or reject the article. He MAY do this
      manually, or else partially or wholly with the aid of appropriate
      software for whose operation he is then responsible.  If the
      article is a cancel nessage (7.3) issued by the poster of an
      earlier article, then he is expected to cancel that earlier
      article (in which case there is no more to be done).  He MAY
      modify the article if that is in accordance with the applicable
      moderation policy (and in particular he MAY remove redundant
      headers and add Comments and other informational headers).  He
      also needs to be aware if any change he makes to the article will
      invalidate some authentication check provided by the poster or by
      an earlier moderator.

      If the article is rejected, then it normally fails for all the
      newsgroups for which it was intended. If it is accepted, the
      moderator proceeds with the following steps.

   2. If the Newsgroups-header contains further moderated newsgroups for
      which approval has not already been given, he adds an indication
      (identifying both himself and the name of the group) that he
      approves the article, and then forwards it to the moderator of the
      leftmost unapproved group (which, if this standard has been
      followed correctly, will generally be the next moderated group to
      the right of his own). There are two ways to do this:

      (a)  He emails it to the submission address of the next moderator
 (see section 8.2.2 for the proper method of doing this), or

      (b)  he rotates the newsgroup-names in the Newsgroups-header to
 the left so that the targeted group is the leftmost moderated
 group in that header, and injects it as below (thus causing
 the injecting agent to email it to the correct moderator).
 However, he MUST first ensure that the article contains no
 Approved-header.

        NOTE: This standard does not prescribe how a moderator's
        approval is to be indicated (though a future standard may do
        so).  Possible methods include adding an Approved header (or a
        similar but differently named header if method (b) is being
        used) listing all the approvals made so far, or adding a
        separate header for each individual approval (the header X-Auth
        is sometimes used for this purpose).  The approval may also be
        confirmed with some form of digital signature (7.1).

   3. If the Newsgroups-header contains no further unapproved moderated
      groups, he adds an Approved-header (6.14) identifying himself and,
      insofar as is possible, all the other moderators who have approved
      the article. He thus assumes responsibility for having ensured
      that the article was acceptable to the moderators of all the
      moderated groups involved.

   4. The Date-header SHOULD be retained, except that if it is stale
      (5.1) for reasons understood by the moderator (e.g. delays in the
      moderation process) he MAY substitute the current date (but must
      then take responsibility for any loops that ensue). The Message-
      ID-header SHOULD also be retained unless it is obviously non-
      compliant with this standard.

        NOTE: A message identifier created by a conforming posting or
        injecting agent, or even by a mail user agent conforming to [RFC
        2822], may reasonably be supposed to be conformant (and will, in
        any case, be caught by the injecting agent if it is not).

   5. Any variant headers (4.2.5.3) MUST be removed, except that a
      Path-header MAY be truncated to only its pre-injection region
      (5.6.3).  Any Injector-Info-header (6.19) or Complaints-To-header
      (6.20) MUST be removed.

   6. He then causes the article to be injected, having first observed
      all the duties of a posting agent.

        NOTE: This standard does not prescribe how the moderator or
        moderation policy for each newsgroup is established; rather it
        assumes that whatever agencies are responsible for the relevant
        network or hierarchy (1.1) will have made appropriate
        arrangements in that regard.
