				moderation:
					* Channel has skip_moderate disabled
					* This is a blog comment, and the blog channel has moderate_comments enabled
					* This is a group starter/reply/comment, and the group channel has moderate_topics enabled

					* Channel has skip_moderate = 0
						This means that even blog entries will be flagged for moderation if skip_moderate = 0
						on the main blog channel and the blog owner, for some reason, is missing canmoderateposts
						on their own blog channel.
					* Blog comments
						Again, if the blog owner, for some reason, is missing canmoderateposts on their own blog
						channel, their own comments will get flagged for moderation.
					* Group posts

					* Finally, for blogs & groups, the channel having skip_moderate = 1 will NOT allow bypassing the
					blog/group specific moderation rules (moderate_comments, moderate_topics). And vice versa,
					even if the blog/group specifically did not set moderate_comments & moderate_topics, having
					skip_moderate disabled on the channel(s) (or or inherited channel) will put the comments/posts
					into moderation.
