It would seem they would be an even bigger target given they accept funds for "fast" downloads.
EDIT: btw, I tried to use anna's archive a few times and couldn't download the files. Something always broke before it finished. Definitely a way less good experience compared to libgen.
Anna's Archive is being sued, the court case has been going on for months [1].
Unlike this Libgen court case, they likely identified the owner, Maria Dolores Anasztasia Matienzo. It's not just another court case against anonymous unidentified persons. They found her due to her poor opsec (nickname was anarchivist), so it may shut down soon.
This is a civil suit, so only a >50% likelihood of guilt is required. The circumstantial evidence is pretty convincing IMO unfortunately.
1. The name, Anna's - Anasztasia.
2. That Anasztasia has the nickname Anarchivist and is a self-described archivist.
3. That Anasztasia had a GitHub WorldCat scraping project.
Perhaps there were more things I forgot. Her personal blog writing reads very similar to the AA blog to me too. I unfortunately think they've found the AA owner.
Thankfully Anna's Archive is fully open-source, so it'll likely live past this civil case in some way.
