Why aren't we violating copyrights when we contribute to the "Quotes" page of films and shows?
The copyright notice of a screenplay I found caught my attention just now. I searched for the screenplay so I could verify and resubmit a declined contribution to the "Quotes" page of a certain film. In standard language with which we're all familiar, the notice says, "© 2012 REPRISAL FILMS LIMITED. ALL RIGHTS RESERVED. NO PORTION OF THIS SCRIPT MAY BE PERFORMED, PUBLISHED, REPRODUCED, SOLD OR DISTRIBUTED BY ANY MEANS, OR QUOTED OR PUBLISHED IN ANY MEDIUM, INCLUDING ANY WEB SITE, WITHOUT THE PRIOR WRITTEN CONSENT OF REPRISAL FILMS LIMITED." [emphasis added]
That prompted my subject line question: Why aren't we violating copyrights when we contribute to the "Quotes" pages? Does IMDb have some blanket agreement with the entertainment industry, either tacit or official? Or, is it a "Don't Ask, Don't Tell" or "Look the other way" kind of thing?
