Blog settings control whether comments are disabled, available to every shopper, or limited to signed-in customers. When moderation is enabled, new comments stay pending until a team member approves them.
Disabling comments hides existing comments on every storefront; they return unchanged if you enable comments again. Signed-in customers comment under their account name. To keep one visitor from flooding your blog, each shopper can submit only a few comments per hour, within the store's overall hourly limit.
Review comments
In your store admin, go to Content, Blog, then Comments.
Filter the list by pending, approved, spam, or trash.
Open a comment or select several comments.
Approve them, mark them as spam, move them to trash, or delete them permanently.
