Code Monkey san
Please keep investigating Ninja server(Ninpouchou server). If I offend you, I am sorry, but the day before yesterday, you said "So far I have found nothing that logs user details beyond what is necessary for the ninja system to work correctly." However, hearing the suggestion that "what is terrible is the form of Zip text file of each ninja ID's writing history is exactly similar to "maru.txz" which was released last August!", you investigated the Ninja server again yesterday. As a result, you discovered many new things, like compressed archives which might be the logged data of Ninpouchou (which you have already removed from server), or the line of code which mightbe concerned the leak of last August.
So, I strongly hope you to keep investigating Ninja server. There might be something crucial which have not been found yet. I feel that Ninja server or Ninpouchou is the blackest box even in this black box named 2chan.
