If you are overwhelmed with tons of comments and you decide to stop them from appearing, use our Auto-moderation.
Go to the "Auto-moderation" module in the menu on the left. Follow the steps you already know - how to create a rule.
When comments appear, they can be deleted immediately. Configure your rule and define Message type and Condition. If you want to delete all comments, select "organic comment" and condition "all".
In the next steps, define the action of the rule to delete. Save the rule and relax. No unwanted comments will slip through :-)
Remember that deleting content is a permanent action that cannot be undone. Alternatively, you can hide comments and make them public again if necessary.
