If not, maybe it should not constitute a valid case in court.
Also, I'm wondering if they are not themselves liable considering they have every copyrighted work in there too.
Persumably there is already a law around why I cant just go borrow a book from my library, type out some 95% regurgitated varient on my laptop, and then try to publish it somewhere?
Edit: I looked it up and the thing that stops you from publishing a bootleg "Harold Potter and the Wizards Rock" is this legal framework around "The Abstractions Test".
