I think this option of allowing sending to oneself should be disabled so that someone won't thinking asking this same question next time. I am sure he must have tried sending himself over time but couldn't succeed that is why he raised this topic to know others option why he couldn't succeeded sharing to his profile back.
No I'm not greedy, Nor I tried to send myself any merits. It was just a simple question. You can't just tell from first sight he is greedy he is bad etc. As for your information I shared my sMerits to other users whom I saw fit. You can check it yourself. I was only curious.
