There is no option for comment moderation in my blog's settings. My Comments Settings only includes the option to change Location.and
I don't get notified about any comments published against my blog. There is no Setting for Comment Notification Email, either.These owners are discovering one of the design simplicities in Google+ Comments.
With Google+ Comments, anybody can post - and share - a reference to any content, on the Internet, that they can view. If your blog is public, any post from your blog can be shared in Google+.
If someone shares a post from your blog, and you are in a Circle where the post is shared, you may see the shared post in your Google+ stream. You have no control over content in your stream - even if the content references your blog - which you do not share.
You have no control over content about your blog, which you, yourself, do not share.
If somebody comments on a post shared from your blog, and you are in a Circle where the post is shared, you may see the comment in your stream. Again, you have no control over a comment made against a post in your stream - even if the comment references your blog.
In no case will you have the opportunity to moderate either a post, or a comment against a post, if someone else shares a reference to a post from your blog. Nor will you get a notification, if someone shares a reference to a post from your blog. Your blog is just one object of interest, from the millions of shares published by people in Google+.
If you, yourself, share content from your blog, you will own that share - you can control the content in the share - and you can control any comments placed against that share.
If someone reshares what you share, that reshare becomes the property of the person resharing. If you are in a Circle where your share is reshared, you may see the reshared post in your stream. Again, you will have no control over the reshare - or any comments placed against the reshare.
If you are not in a Circle where your share is reshared, you won't even see the reshare. Even if your blog is referenced in a reshare, your blog is just one object of interest, in the millions of shares published by people in Google+.
Notifications work the same way. If you share content from your blog, you will get Notification when someone comments against your share - or when someone reshares what you share. If someone else shares - or reshares - content from your blog, which you did not originate, you won't get a notification.
With Google+ Comments, a post in your blog is treated like any time anybody shares a post from your blog. You own a post in your blog, just as you own a post which you share from your blog. You can control comments, when made directly against a post from your blog, as with a post shared from your blog.
If your blog uses Google+ Comments, you can moderate the comments by viewing comments on a post by post basis, and deleting what you don't like. You will get no ability to moderate comments before they are published - even if the comments are against your blog. Nor will you get notified when someone publishes a comment against a post in your blog.
Your blog has no comment moderation wizard, no settings for comment moderation, and no settings for comment notification, because you have no ability to moderate comments - nor do you get notifications.
Google+ is pretty much like real life. You can hear what people say about you, when you're in a real life conversation. You can't control what people say about you, behind your back - and you're generally better off not even knowing what people are saying about you, behind your back.
Concentrate on listening to what people tell you, or reading what they share with you. Ignore what you can't control, or hear. Get on with your life. Or, revert the blog, back to Blogger native comments.
