Making Light:  SFWA:  DMCA abusers ::: September 08, 2007, 06:40 PM

Dave Langford (#429):  '...the group itself was then deleted, with
email to the members explaining that as "As a gesture of goodwill,
we have removed all the documents added to the copyright violation
group."; (d) no document which I added or remember being added to
that group has in fact been removed from Scribd.  The experience is
not wholly unlike being lied to.'

Not wholly unlike, but not wholly like.  I'd say it is the result of
Scribd learning that they cannot accept even well-meant third-party
takedown requests, since third parties may be uninformed of the
copyright holder's intentions.  I suspect they will accept first-party
requests without proof of identity--have you had trouble getting your
own work removed?

What is missing is a way for a copyright holder to issue a blanket
proxy for certain works to be removed upon discovery.  The discovery
of the works should probably be carried out automatically.
