Oh well I wasn't aware that it hadn't been translated by one.
It seems a bit strange that a series ranked so highly on "My Anime List" hasn't been fansubbed. 
It's a scoring aberration. Its high ranking can be chalked up the fact that it's only been seen by a small/dedicated fanbase that are likely to rank it highly. With only 1353 members voting for it, it's definitely an anomaly in an area of the rankings dominated by titles with at least 5,000 votes. Most of the upper-echelon titles have 10000, 50000, or even more votes. You have to go all the way down to
#167 to find an anime with a similarly low vote count (1399 votes). The next title with
fewer votes is ranked
#397 (777 votes).
So basically, high ranking on MAL and other sites does not ensure that a title is popular or well-known enough to be subbed.
