I sometimes see answers in the review queue that have apparently been flagged/voted for deletion with the boilerplate comment "this does not answer the question...", or something to that effect. In the vast majority of cases where I encounter this, the post actually does answer the question. I suspect they are flagged because the answer is either wrong or short and lacking references. Is this a valid reason to delete answers?
Similarly, I occasionally (rarely) see answers which are later moved to comments. I think this is done by moderators because the answer is short (correct me if I'm wrong). If short answers should not be deleted, should they be moved to comments?
Here some related/duplicate topics:
I bring this up because those posts are rather old and I think it needs to be discussed again.
Here is a current example I came across in the review queue of a post that directly and correctly answers the question but has been flagged. The answer was subsequently deleted.
