Publishers say Anna's Archive hosts over 140 million texts, making it one of the largest "pirate" libraries online.
The site reportedly described themselves as pirates not bound by the law, boasting 763,000 downloads in a single day last week.
It's also accused of selling high-speed AI access to AI developers, and a company was found to have torrented content from the site.
Despite losing some domains and facing earlier lawsuits, including one over Spotify tracks, Anna's Archive is still running, now embargoing its Spotify/music file release while waiting for a court decision.
