By default, anyone can post a review on your product page. While this can boost the number of reviews you get, it also opens the door to potential spammers or competitor-driven attacks.
To prevent this, you can limit who can leave a review and allow only actual buyers to review your products.
Web reviews restriction
From your Judge.me admin, go to Settings > Review Widget > Review Curation > Web Reviews.
Enable web review restriction. This will hide the Write a review button for web visitors. Reviews can still be submitted through our review request emails or via API requests.
For added protection against spammy automated reviews created through API requests, you can activate the Heavy Restriction feature.
