This is a continuation to Is it OK to answer old questions?:
What should we do with new but redundant answers to old questions that already have very good accepted answers?
Obviously, if the new answer adds something to the existing answers, all is well and good.
My question is about a recent activity by a specific new user who keeps adding redundant answers to old questions that are just a rehash of the existing answers. If others take up the trend, we risk becoming a second quora - with dozens of almost identical answers.
Obviously, we already have the mechanism: if one thinks that the answer is poor for whatever reason, one can downvote it or flag for moderator attention.
My question is about the community attitude to such activity: should we actively discourage such answers - and ask moderators to remove them - or should we ignore them?
