Here is a response to the question from Franklin:
“The short answer is that we wanted to keep process on the site as simple as possible. Because you can buy evaluations on the Black List website throughout the time your script is hosted there, you could theoretically always be “waiting for feedback,” which begs all kinds of questions about whether the script should be public or private during that period. So we opted to go with a simple binary: if you’re hosting a script on the site, the script is available on the site. Feedback is effectively a separate mechanism that can raise the visibility of your script on the site if it’s well received, but regardless you always have the option of keeping that feedback private whenever you do receive it.”
I will convey your further thoughts to him.
