In other words, giving your book to somebody in good faith but the person then pirates it will cost you $300'000 (or at least it did in this case with Caridi and DVD screeners).

In other words, you better not share, unless you've got a lot of money laying around...

Interesting. Pre-release screener copies, which you're presumably not even allowed to show friends, would seem like a different kettle of fish than files which are publicly available for purchase.
