Junip always needs to associate a review with a real individual (ie no bot, spam, fraudulent content). In most cases we already know who a customer is because we're sending them a review request email, so there is no "verification" required.
In some cases where there is a publicly accessible form (such as the write a review button within product page widgets) we need the reviewer to confirm their identity by clicking our confirmation email.
The difference between a confirmed review and a verified review is as follows:
Verified buyer review
A review that has been submitted and matches to a purchase made on your store will be considered a verified buyer review. Verified reviews are given the "Verified Buyer" badge on-site.
