We're arashiproject and we work in reuploading the dead subbed files made by old subbing teams, in the respect of their rules.
We have opened a new masterpost for hatenai_subs, you can read everything in this entry. Although we focus mainly on Arashi, they subbed A LOT of HSJ videos as well :)
If you have any of the missing files, please don't hesitate to share :)
Thank you for your help and support :)
