I have seen many questions and answers in which a link is provided and after a while, the link is corrupted, out of date, changed or currently is not accessible.
Unfortunately, there is no bibliographic citation included in the posts to chase the linked content, users usually only have the link on their posts.
How should these types of posts be edited, should that link be removed or the link should be remained unchanged?
PS: Some links may be temporarily unavailable and will be working in the future; so we should avoid to edit links instantly.
