Since the last 2 days, I am getting a message in my SO Inbox with the comment below for my previous answers where I have suggested only a link as the answer.
While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference. Link-only answers can become invalid if the linked page changes
Interestingly these comments are from different users on different answers.
Is this is done automatically by Stack Overflow staff, or is that a bug?
