Once user generated content is reported as abuse it will show up in the administration backend where store owners and managers approve or unapprove content.
The approval workflow is available both on the product level and more importantly on the store level as well to make sure that the process of approving reviews is as efficient as possible. Reviews can be removed at any time at the store manager’s discretion.
When viewing the “Pending Reviews” tab on each store only reviews and comments, which require attention are displayed. While everything is displayed on the product level.
Should you want to have all reviews and comments screened before allowing them onto your website, you can indicate so on each of the stores by ticking the “Product reviews require approval” check box.
