The question What is a whip stall? just had some activity I've never seen before. It is showing on the home page saying that Rick Bennett, an unregistered, 1-rep user with no questions or answers and no accounts on other sites, "modified" it. In the history, it says that Community protected it, at the same time that the home page sais Rick Bennett modified it; the history page says nothing about Rick Bennett. Neither the question nor its one answer has been edited by a user with the name Rick Bennett.
What happened to this question? Did "Rick Bennett" really do something with it? Why did Community protect it after seven years of inactivity?
