Newly unsealed emails allegedly provide the “most damning evidence” yet against Meta in a copyright case raised by book authors alleging that Meta illegally trained its AI models on pirated books.

Last month, Meta admitted to torrenting a controversial large dataset known as LibGen, which includes tens of millions of pirated books. But details around the torrenting were murky until yesterday, when Meta’s unredacted emails were made public for the first time. The new evidence showed that Meta torrented “at least 81.7 terabytes of data across multiple shadow libraries through the site Anna’s Archive, including at least 35.7 terabytes of data from Z-Library and LibGen,” the authors’ court filing said. And “Meta also previously torrented 80.6 terabytes of data from LibGen.”..
