Initially I assumed this was a strange coincidence or a bug in the system. But then I realized the two questions were literally exact duplicates.
Same title, author, comments, answers, migration path, top answer, and related posts.
Even the vote counts for comments and answers are similar between both questions.
Strangely, none of the comments on the prior question are linked to any specific users. Each of the profile names is unclickable, as if the comments were somehow made anonymously, or every user had their accounts deleted.
How is it possible for there to be two exact duplicate questions, including duplicate comments and answers?
