I know this has been said before. I feel like saying it again.
Requiring Sellers to leave public feedback for buyers is pointless and frustrating.
The vast majority of sellers are not going to leave honest feedback without knowing how the buyer rated us.
First, because way too often, (like maybe once every few months but STILL too often) I have buyers who don't communicate whether they are happy with an order or not until it's time for a review. Therefore, I don't know how I feel about them until I see their review. If they are perfectly satisfied, I am also perfectly satisfied. Happy to leave them a good review. If they are not happy with their order, and using a review as the only way to communicate it, I am not happy with them. I've taken to shooting them a message after the order to encourage them to communicate with me, but honestly, it's not a great solution.
Second, because I have a few buyers I work with who are difficult to work with. I wouldn't consider them to be five-star clients. But I keep working with them because I am used to their quirks and they pay me. Why would I rate them honestly? I want to keep working with them. I'm not going to talk badly about them, no matter what.
Now I understand that sometimes there are phenomenal customers who deserve a great review. And sometimes there are buyers who are just bad, and taking the time to write them a bad review is a good service to the community. In both of those cases, I think a seller would willingly write a review. But requiring one in order to see the customer's review just isn't productive.
