Auto – Trust Commenters
Automatically Trust Commenters From Logged-in Or Registered Users
With Shield you can automatically trust comments posted by logged-in or registered users. Simply specify user roles that will never be scanned.
Shield doesn’t normally scan comments from logged-in or registered WordPress users. You can specify user roles that shouldn’t be scanned. Or even set how many approved comments must exist before a commenter is trusted and their comments are no longer scanned.
