I thought about that user, but decided not to nominate him. The good thing he did was only a week ago, and that's why several people remember him. If this nomination would have been half a year later, chances are he wouldn't be the first one to think of.
You can take in this way that he did something too good which make us forget the other nice things being done by the others. He may stand out even after 6 months or year.
I think he is special because he had nothing to lose except a newbie account if he has decided not to return the money, but he chooses the act which has made him legendary.
