This question already has an answer here:
I just flagged a question as off topic.
I flagged it with the following reason, but I don't think this was quite the right reason for this question:
Questions concerning problems with code you've written must describe the specific problem — and include valid code to reproduce it — in the question itself. See SSCCE.org for guidance.
I'm pretty sure that reason doesn't make sense for that question, but since that question is way off topic, I don't know what reason I should have used. What reason should be used for way off topic questions?
