I was reviewing some closing votes, and I stumbled into a question which seemed ok to me: at most, I would have added a soft-question tag. So I clicked on "leave it open"; a message appeared, saying
«This was only a test, designed to make sure you were paying attention. You passed. For reasonable questions, Leave Open is appropriate.»
Given that in the past I did leave open a number of questions, I wonder what is the use of such a message. I may understand the reason behind the test, but then wouldn't it better not to say anything when the test was passed and showing a pop-up only is somebody did not pass it?
