It isn't uncommon that I will see an answer posted by a new user (often 1-rep) on a question which hasn't been active for over a year. What's more, this question already has an accepted answer. The new answer given is an exact duplicate of an existing one, to the point of being a possible copypasta.
When confronted with this, do we...
- ...downvote it?
- ...flag it for deletion?
- ...comment on it somehow?
- ...leave it alone?
I really don't feel like there's any obvious way to deal with this scenario, though it is not at all uncommon.
