I saw two neighbors between my eyes. Then I lost my right eye, but I was still the same. Then one neighbour left, but I was still no different. Finally, I lost my left eye and now I no longer belong to any culture. Who was I? Edit: Changed the wording a bit to make some points clearer

In this reply a user doesn't obey the non-spoiler policy. I've asked him to reformat and suggested a way to do so but last time I checked, he didn't. How should I proceed (other than flagging and asking here) if I'm not prone to go in and rewrite that for him?
