As far as feedback goes, I don't think it's finished. It may just be a slow week. Also, eBay does state that buyers generally leave feedback two to four weeks after a transaction and this does hold true in alot of cases. As a seller, DSRs are very important to me and something that reminds me to keep trying to be accurate in the listings and offer a good service.

As far as blocks, I think the system should be more steamlined to allow both parties to mutually agree to cancel. If a seller offers a Mutual Cancellation and the buyer turns them down, they should be allowed to open a UPI in the appropriate timeframe. There needs to be a transparency where sellers who have a non-payer can rest assured they will get their fees back no matter what. If buyers were told that the seller actually can be out $10 or more because they didn't pay, they might start agreeing to the cancellation requests. A UPI is too harsh of a route to go. Sellers need a nicer (but 100% reliable) way of getting their fees back.
