A relevant share of the answers which appear in the flag queue are flagged because they contain little more than the link.
Then the usual suspects jump in and add the comments like:
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.
Is there a concensus whether such answers shall be deleted? One might argue that telling the user and leaving the answer is better.
A related question: I wanted to ask whether there is a list of these standard comments. I assumed there may be a community question with a respective collection. Or the users have their own text file with a copy of them... But just now someone told me that this text was inserted automatically by him flagging the answer as low quality and selecting "link-only" as the reason.
But when I flag (no matter whether from the flag queue or directly) I do not get such a selection.
