Diamond moderators regularly delete answers on the grounds that they are unreferenced. (Ironically enough, I can find a FAQ stating that answers must be referenced, but couldn't find any post saying that unreferenced answers get deleted) However, in the help section for trusted users, it says:
When should I vote to delete an answer?
You may vote to delete answers in the following cases:
- The answer is extremely low quality: There is little to no scope for improvement
- The answer doesn't attempt to answer the question; it may be a comment or a separate question altogether.
Does this mean that trusted users shouldn't delete answers on the grounds that they are unreferenced?
