Again all the issues you mention are related to the piracy of american media, not japanese media.
I don't see these american anti-piracy groups send messages like "stop sharing [SVDVD-113] Ultimate Machine Vibration Torture.avi". I know this is also assumptions, but among the trillions of files being shared, there needs to be priorities.
But I am well placed to know that the Akiba-Online admin receives DMCA-like messages from japanese rights holders, though this is only on an occasional basis (the strongest so far was from Prestige, and honestly I doubt we will ever hear from them again).
This is all mostly true.
I would not expect Akiba-Online to see any DMCA takedown requests from DtecNet because of the "Six Strikes Campaign" which major American ISPs' are voluntarily committing to in conjunction with the over-seeing of the CCI, November 28th. Then again, Japanese companies are not paying DtecNet for this service. I also know for a fact that Akiba-Online has gotten take down notices from American companies that have had an invested interest in what has been shared here. Akiba-Online takedown requests are not the issue here though.
What is at issue is that if DtecNet software detects someone downloading, for example: "[SVDVD-113] Ultimate Machine Vibration Torture.avi" via bittorrent are they going to report this as an illegal download to the participating ISP? I think it is a distinct possibilty because
now someone is paying DtecNet to monitor potentially
any illegal bittorrent activity. This has been a technique used by anti-piracy outfits in Europe, (the orgin of the "Six Strikes campaign"), in the past and I have seen
no evidence that the complaints to an ISP have to be limited to MPAA and RIAA concerns. I would like to see proof otherwise and put my own mind at ease.
Again, it depends on what type of tracking software and how accurate it actually is. Just by downloading via bittorrent could put you at risk of an erroneous and false complaint. You could be downloading a JAV file and be accussed of downloading the "Expendables", (perhaps because someone else downloading the same JAV file was also downloading the movie?). The burden of the defense would be with the downloader, if any defense is even allowed or accepted.
So I do not see this affecting Akiba-Online directly nor do I see this affecting bittorrent users outside the US but I do see it as affecting Akiba-Online members who live in the US and a test of bittorrent tracking software in general. I live in the US so I was drawn to comment on this as I myself likely am affected. I did not mean to worry any non-US members as this should not affect them.
