You probably should get really angry, cuz you seem to have a insider's view into Scribd's back end. If not, then you're just bloviating and making strawman arguments that don't really stand up.
I submitted here to HN a link to a PDF which is
copyrighted. That has been uploaded to scribd
without acknowledgement. When I contacted scribd
to ask them to take it down they said it was the
responsibility of the copyright owner to make a
formal request for takedown.
Who ticked the box? I certainly didn't. Who checked
that the person ticking the box had any right to do
so? Scribd certainly didn't.
Scribd make no effort to ensure that copyright is
not breached. There is no traceability. Their
"efforts" are ineffective and insufficient.
Someone has uploaded copyrighted material to scribd, and it's still there. Hence I conclude:
If someone uploads material to scribd in breach of
copyright, there are no sanctions, there is no
culpability.
No, really, I would, and I'm just being selfish. Currently I get very angry thinking about their existence, and if I learned that I was wrong I'd be happier.
Please.
If you can't, then I suggest that when you say:
