Note that with A DMCA take down the original uploader can issue a
counter-notice to get the content put back. Most sites don't
immediately delete the content but rather disable it in some way
so that should the file be counter noticed it can be put back up.
Also, when using a hashed file store, it's possible that some uses
are infringing and some are not. I might make a movie, put it on
Megaupload, and then give the links only to the 5 people who bought
it from them. One of them might turn around, upload it again to
Megaupload, and share it with the world, infringing on my content.
I would hope that when I issue a takedown notice they take down the
infringers copy (link), but leave mine in place.
None of this should be taken to mean I'm behind Megaupload. I have
a greater concern here wondering if law enforcement, the courts,
and most importantly the law makers understand the technolgy and
can craft and apply laws in a reasonable way. One major issue that
already came up is that a whole lot of people used Megaupload for
storing perfectly legal content. It's now offline, and there appears to
be no way for them to retrieve that data. At what percentage is that
reasonable? If 99% of your users are infringing? 50%? 1%? Could this
be used to take down your competitors? Buy some Amazon instances and
put a bunch of infringing content on them, and then watch the feds seize
all of Amazon's servers?
Lots of troubling questions, no good answers.
