Moderation
Approve, hold or remove comments which need review.
Moderation is the working queue for comments which are not ready to appear publicly.
Review pending comments
Check the content, links and thread context. First-comment moderation can hold a new participant until a moderator has reviewed their first contribution.
Be consistent
Use the same rules across participants and document site-specific moderation policy outside the individual comment where appropriate.
Links
Sites can choose to moderate comments containing links more strictly. This helps reduce obvious spam without blocking ordinary discussion.
