It's just that if some students have some homework to do about this poem, they could just find the information here and pretty much cheat.
I think that's why Cas is against the idea.
I think it's ok to be vigilant about this issue. I know nothing disappoints me more than finding out my students copied on their homework.
I guess this means requests that look like assignments will be rightly frowned upon.
The actual motive is not really important (I mean the reason why you chose to analyze this poem). At the end of the day, it looked like an assignment.
It's like asking: "Hello everyone, I've lost my serial number of windows xp, could anyone give it to me?"
Even if you did lose your CD-Key, it would still look like a piracy request and would be denied in most places on the internet.
Don't take this to heart. Maybe you can find different questions to ask about a poem next time.
