No, it's not a joke. If someone wants to cancel, the least they can do is accept it. I shouldn't have to wait 8-10 days before I can close the cancellation because they decided they didn't want it any more. If they accept the cancellation, I can relist straight away. It's a 2 way street. There are plenty of people who are worried about black marks on their account, especially low feedback buyers, who seem to be the ones that change their mind after they've paid. If they change their mind and haven't paid they get hit with an UPI.
