This is a not a duplicate of How should we flag link-only answers?
I want to propose the mods to create the flag for 'link only answer' in the answer flag to simplify flagging them. They are occurring with a very high frequency of late.
I'm talking in cases where a user has asked a valid question and another user is trying to answer it. But the answer given is something like:
Check out http://example.com/some-link.
The linked article or blog can theoretically answer the question but I don't think this is advisable especially after reading Are answers that just contain links elsewhere really "good answers"?
