@AnnaLear I understand what you are saying, but somebody not liking all the topvoted example questions is a slight bit unlikely, compared to a malicious troll. Just reading the 18 questions and evaluating them would have taken around 10-15 mins. Is it possible to check the times' when the downvotes were cast? If they were cast very closely together, say within 2-3 minutes, then it surely would have been with malicious intent.
