I flagged this answer as not-an-answer, because it contains nothing useful except an off-site link which is now broken.
My flag was disputed and the "answer" remains.
I was under the impression that answers containing nothing but an off-site link were not allowed; has this changed? Are we to consider answers which contain no useful information and a single broken link to be valid answers?
I flagged two similar no-content answers and both of those flags were also disputed (though one was deleted anyways). Is this a case of somebody with access to the mod tools not understanding SO's policy on link-only answers?
