Some audience contributions (comments) are manually pre-moderated, meaning human moderators manually review submissions before posting. This process can create a lag between the time the comment is submitted and the time it is published on the site. If we are experiencing a high volume of submissions that require manual moderation, the delay may be more noticeable.
From a technical standpoint, our system does not allow us to hold back posts of a certain viewpoint over others. Our pending queue is akin to a fire hose; it is a continual flow of messages. For submissions that require manual review, our moderation team does their best to address all those submissions as quickly as possible and we have multiple moderators working on the queue at any given time.
While you are waiting, you should see the message, "Awaiting Moderation" (see sample image below).
