I am sure I edited this question earlier today.
I asked the OP for clarification (Do you mean 'hibernation'?) and edited his response into the title, among other things.
But I see no rollbacks, no denied flags, no edit or comment history (nothing in my All actions list), no search hits on 'hibernation', no duplicate questions from the author, nada....
I checked the same clues at Productivity.SE because these kinds of questions are asked there too (and the user has no questions there).
So, out of curiosity: What (can have) happened?
Maybe if a user deletes his question and writes it again there are no traces left to see for others (below 10k)?
Or a rollback of some kind happened?
