Comment Assuming Infringement by Default (Score 4, Interesting) 130
The default assumption of these automated checkers is that anything shared is infringing.
I've run into this myself. While I give away my book Modern Perl free in electronic forms, my publisher charges a nominal fee for the Kindle version to cover expenses. I made some changes recently to fix some formatting problems and edit out a couple of typos. After I uploaded a new version, the Kindle copyright police declined the update (to a book they'd already allowed in their store) because they thought it was available online for free elsewhere.
I understand that no one wants a million copies of Wikipedia articles clogging up book stores, but it would be nice if there were a way to say "Yes, the contents of this book are available under a Creative Commons license and I have the right to distribute it."
(My publisher has the same right to distribute the printed copy, and Amazon is very happy to sell that version.)
