We had a (now-deleted) answer to this question that was at +28 with the author requesting that it be un-accepted so he could delete it. On the other hand, the comments explaining how it was bad had been upvoted to the fifties.
This is not the behavior voting should result in. The answer was known bad, and yet yielding upvotes, but the votes in the comments were logically outweighing the votes in the answer showing its badness. But the answer downvotes didn't come.
What have we done wrong?
Two answers; both miss the point. There is no problem with deleting the answer. There is no problem taking awhile in identifying the answer was bad. There's an obvious problem when the comments on why the answer was bad got more upvotes than the answer ever did and the answer is still net highly upvoted.
