Recently on the Music site we had this answer posted to a question asking about sheet music resources. (I don't think the question is a good one, but ignore that for the moment.) The answer did answer the question, providing two sites with a decent description.
However, the bulk of the answer is editorializing on the legality of sheet music sites, copyright, and so on. The current policy is that legal issues are off-topic. Asking a question that solicited this sort of discussion of legality would be off-topic.
I feel comfortable saying that editorializing answers are bad and should be downvoted, but they also seem to be a way to subvert the scope of the site as determined by the community. As such, are they an issue of moderation?
- Is the answer also "off-topic"? How do we distinguish between questions an answers in that regard?
- Should the answer be deleted?
- Should the answer be edited to remove the "off-topic" portion? If edited back to its original form, should it be reverted and locked?
