Whatever the reason might be. Posting the entire series 3 times, ensures links will be active for a while. It's doubtful that was the intention.
It's too bad file sizes from this uploader continues to be A.bloated beyond need and B. encoded with a non standard codec.  Audio has been good every time. It is more important than video.
Anyone that knows the history of Anime encoding. 350MB is the more than enough to ensure a great looking and sounding file that fits on a single 4.7GB dvd-rom. And will work with most Divx labeled DVD players and external media players.  A series must be high rated if it will survive a bigger file size. The rest are quickly forgotten soon after posting.
