I have interacted with a few new user recently who are very disgruntled due to getting a lot of downvotesdown-votes on there questions for been duplicates.
I don't downvotedown-vote these myself but I can vote to close, so I feel I don't have to.
I think it may be very counter productive, the downvotesdown-votes without the context of explaining why (the users are new, they don't understand duplicates) are annoying these users and some will not come back, no matter how much someone tries to explain after the fact.
Not all duplicates are obvious, especially to those without experience or technical knowledge. I think it would be good for these first timers to get an explanation of what they did wrong rather than just downvotingdown-voting them in to oblivion.
I know this is a duplicate but it is becoming an issue again and I did not know how else to bring it back up.
