This question has been closed as Off-Topic (I cast the final vote). There is this discussion on Area51 in regards to translation questions but there doesn't seem to be a definitive guide on whether we should consider these on-topic or not.
The highest voted answer on there is:
I don't think this site should function as a translation site. However, online translators often translate word-for-word, and the resulting translations often sound notoriously unnatural. So I could see presenting a piece of translated text, and then asking if that translation sounds on the mark, or asking if it flows naturally, or if could it be improved. Such inquiries might be very legitimate.
This answer seems to be on the fence saying that we should accept some, but not others.
So should we accept translation questions and if so, what are the guidelines for them?
