How would your reaction be if you see a question "Send me ...." and the answer is "done" and the poster of this "done"-message receives 10 points for correct answer?
Point allocations aside, I've noticed this too. One person starts with "can u pls send me..." and the kind person wanting to help replies with "advise me of your email". Suddenly, a heap of people just in with "send to me too".
How do I react? - I press Alert Moderators 
If anything to avoid this from happening
