I came up with this question due to a first post review to which I didn't really know how to handle exactly.
I had to review an answer to an old question that would (most likely) be off topic with current site standards (asking for library recommendation). After thinking a bit I didn't know how to exactly review the answer, after all it's barely more than a link only answer but when you check the other answers to the question you see that they are the same and voted up.
Since the answer is actually on topic for that question, seeing that it's the same like the other answers on the question and as not to confuse the new poster why his answer was down voted when it's just as good as the others on that question, I decided not to do anything with the answer for now. Instead I flagged the question as off topic so that it'll be closed and can't get more off topic answers.
Is that the right thing to do? Should I also down vote the answer?
