Thank you for reporting it!

I've actually seen this particular question before. It's hard to figure out why some questions get bad or wrong answers. This question also doesn't have a proper reference.

I think it's difficult to get the initial result perfect 100% of the time. So far, my solution to this is an upvote/downvote system. This lets me either hide downvoted questions, or improve them. Right now a user who downvoted can report an issue, and I will generate new variations of the question. If either of the variations receive enough upvotes, the question will be updated.
