This question already has an answer here:
in my attempt to review, i discover that the thing that seems to occur most often is that new users with 0/1 reputation are answering questions that have accepted answers and are years old, and the answers say almost exactly what previous answers said, and there is no activity on the question for a long time. often, one of the answers has 10+/50+ upvotes, and still the new user is attempting to add an answer.
it would seem helpful if there were a "duplicate answer to old accepted answer" in the following dialog, because the situation is not that it is not an answer, and not that it is "poorly formatted" (though i suppose it sometimes could be considered a "content problem"). it is really merely that it is adding nothing to the discussion except noise for a question that has an accepted answer and isn't really going to get upvotes since it's really identical to an existing answer.
