We have a question about how to apply the back it up principle here on Politics.SE. Although there is no accepted answer, the top answers all suggest that answers should be generally (but not always) backed up. The most common way to back up an answer is with references. However, many (if not most) of our answers are not backed up.
Do we have the ability to use this post notice? If we do, should we use it?
