Keep in mind that the Fame Box page is merely a player's "Best Guess" as to what gives fame. It is no more authoritative than any other player's guesses. It is much sexier, though. 
When Gsklee started Fame Box, he tried to keep it to confirmed fame only. As far as I have seen, it has mostly stayed that way. But even so, although we know that there is a'Trader" fame point, and 3 "Legendary Hero" fame points, the exact details of how you get them may still not be known.
I'm about 95% certain that I got the trader fame--sold food for 50g/100 profit to a starving City, and got a fame point.
