> 95%+ of orders receive 5 star reviews

This is going to be subject to Goodhart's law[1]. As soon as buyers are aware their favourite sellers on Etsy are evaluated like this many of them will always leave 5 star reviews, while others will try to use the threat of a < 5 star review to get special consideration from the vendor.

This is the same reason many people leave automatic 5 star reviews for gig workers unless something goes grotesquely wrong.

This was my first thought. Now that I know that's how it works, I'm unlikely to give below 5 star ratings unless my experience is really bad
