If you go to this URL, you’ll notice that the top result, Mentor Turned Tormentor, says “Author Hidden” in the Author column. When you go to the actual story, however, the author is public. As per our discussion, this is a leftover from the story challenge.
Thanks for notifying me of this. This is not intentional, but I can’t promise when this will be fixed. Not too much in the future, I hope.
