I saw a question I asked a while ago that had already been answered posted today with the same answer but from a date and time I definitely did not write it
i get asked the same questions a lot, but if the wording seems too exact to be plausible then i would bet that someone copied it on purpose. i've seen those types of hi-jynx before. i suspect it is to either test what happens or to see if i would answer it again without noticing. which, to be honest, after doing 100,000 questions or more is quite plausible
