I have flagged 4 exact duplicates yesterday https://math.stackexchange.com/users/flag-summary/86800 leaving only one version Integers and integer functions
And today a yet another exact duplicate has appeared!
https://math.stackexchange.com/questions/966952/function-and-two-numbers
I would say the question was $95\%$ answered a few times, but this user does not seem to be willing to make any effort an all, he just asks the same question again and again...
Is there anything that can/should be done about it, other than raising a yet another flag?
