I recently had one strange experience.
I and 2 more users had answered a question and all of sudden all answers were down voted.
filter product collection by a comma-separated attribute
I then noticed that someone had marked as duplicate.
I then doubt that it might be feature that, if someone marks a qst as duplicate then all answers penalised.
My Question
I personally don't think this is a feature, but if it is then how can a user find out whether it is duplicate before answering it?
