Sadly, this was likely the result of a combination of "Fastest Gun in the West" syndrome and "Let's all pile on everyone else thinks it should be closed so I do too." Sadly reviewers often fail to review properly which in my humble opinion goes like this:

1) Read what you are reviewing.

2) Follow the link to the original question and read everything to gain context.

3) If there is an accepted/upvoted answer, clearly the question was understood by someone, who should edit it for clarity if at all possible.

4) If the question is understandable to you but might be confusing to others, edit it for clarity.

5) If you can provide a better answer than what you see, do so.

6) If you see an answer that looks promising but could use improvement leave a comment encouraging that improvement for the answerer.
