First of all, why are you putting other people url's into focus when you know that's not allowed. Second of all I cannot find that site in the top 100 results for any topic in it's categories - I have checked (just a dozen or so).
The only thing I see different with the URL you mentioned and your own directories that were hit are:
They give attribution to dmoz.
They show the actual listings without a 1-1/2 page down scroll down past the ads?
Define legitimate please. If you have multiple copies/mirrors of the same site, or very high percentage of duplicate content taken from other places you have something to worry about – if you don't, there isn't anything to worry about…yet.
