WP Rich Snippets Anonymous User Reviews
It is necessary for us to provide users with the option to remain anonymous at times. It will make the name and email field fully optional so that Reviewers can write a review without having to disclose their Name or Email address and remain anonymous. The Anonymous add-on will allow you to accept anonymous user reviews on your website. It will also make it possible for you to accept reviews from users who are not logged in.
Add-on Settings Page
There are a few different configuration choices available for the add-on on the settings page.
It would not be a problem at all if you ever needed to completely delete the Name and Email fields at some point in the future. It is possible to fully remove the Name and Email fields from the form using the Anonymous add-on; the options page for the add-on makes this adjustment simple and straightforward.
