You originally flagged this as "not an answer." I agree with the action of declining that flag, because it is indeed an attempt to answer the question, if not a great one. We are being a lot more strict with these flags now, in large part because of how they are used in the audits. "Not an answer" flags generally should not require us to read the entire question for us to process them.
I went ahead and marked your second flag as helpful and deleted the answer, although I still have some issues with that flag. Your flag read "It is copy and paste of Jimmys answer from 2012 (s. above)", but that's not really the case here. The answer you flagged reads
select map.txt --> click Properties, change Build Action is None
where Jimmy's answer is
Change the build action to "None" in the properties window for that
file, if you're manually reading it with StreamReader. The message
comes from the content pipeline trying to import it for you.
This is clearly not a copy and paste of Jimmy's answer, so we're not talking about plagiarism here. They are merely restating what Jimmy said, but in a slightly different way. We are perfectly fine with multiple people contributing answers that state the same thing in different ways, if they add something to the existing answers.
However, given that Jimmy's answer was provided a year ago, and this adds nothing to what was already there, I removed the answer to clean things up. A clearer flag might have been to say "This new answer just restates what's in the old accepted answer here, so it can be removed", which I think would have gotten the point across the first time.
