Aggregated review forms offer customers several options for displaying their names next to reviews. One of the options is to leave an anonymous review.
We understand that some shops would strongly prefer to have real customer names next to reviews. There was no "anonymous" option in the early versions of the plugin. However, online privacy is a big thing now (even more with introduction of GDPR by the European Union), so we plan to keep the "anonymous" option going forward. We should respect privacy of customers and let them decide if they want their names to be public or not.
