Apparently there can be 5 sources for the new bumped uncensored files:
1st: they are officially licensed by MS Pictures to hentai.xxx
2nd: an employee of MS Pictures copied the files and sold them on the black market
3rd: a member of the japanese censorship board active for MS Pictures (just like NEVA and such) copied the files during the censorship process and sold them on the black market
4th: the leak is at Trimax
5th: Trimax itself is involved in hentai.xxx
So we are facing a situation where the source can be official or on a pirated base. We do not really know. And we just are talking about MS Pictures as the only involved japanese provider, no other video by any other provider just like Mediabank, A1C, KSS, Mary Jane etc. leaked yet uncensored. Different providers use different censorship boards though.
