That's good snark lather, but if you actually look at the collectorz.com forums, you find that yes, the email WAS as bad as all that: http://www.collectorz.com/phpbb2/viewtopic.php?f=15&t=15...

Done.
Ugh, this nonsense again?
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.
Because "compelling evidence" can be easily fabricated. Just ask all the writers that have had their works expunged from the Internet because an ex-wife, ex-writing partner, or angry reader decided to claim copyright infringement in order to mess with them. It happens all the time.
The valid affidavit requirement in the DMCA is a strong deterrent to this kind of nefarious abuse.
Think what you want about Scribd, the case is really loopy and weird.
