Question : Is it considered ОК to copy-paste someone else's answer to an earlier question as your own, as long as you provide a link back to the original answer?
Background : A question has been posted this morning that happened to be a duplicate of an older question with a rather detailed code in the accepted answer.
Within minutes, two answers (answer 1 and answer 2) showed up, containing the exact copy of the code from the answer to the old question. The only difference between the two answers has been that the first one linked the source question, while the second one copy-pasted someone else's answer with no further explanations.
I flagged both answers for moderator's attention. The "plain" copy-paste flag got accepted, but the flag for the answer with the link got rejected. The only difference between the accepted and rejected flags was a link back to the copied original, prompting my question about the fair use.
