While reviewing I occasionally stumble upon "answers" like this one or this pair of posts. Both cases consist of a question that has been posted as an answer and then has been subsequently answered, although in the second case the thread was practically hijacked by a single user...
Most often, the question is related to another answer and everything can be demoted to a bunch of comments. In some cases, though, this would not really make sense. I normally flag these as "Not an answer", but in some cases I have felt that the content was worth preserving in some form.
It seems to me that the answer in the first case took some effort. Is there a way to preserve it, while maintaining the proper Q&A format?
Alternatively, would it make sense for a reviewer to let posts like this be, in order to preserve the content? I have routinely let some far more useless posts be, simply because they actually were answers, even if it was barely so.
Is there a fine line somewhere, or should reviewers follow a strict "No questions as answers" and flag away, even for years-old threads?
In cases like the second one, should I flag both the question-as-answer and the answering post? The answering post would probably not make much sense after the question has been deleted...
