As a publisher and author I would be extremely annoyed that someone actively promotes those who commit the criminal offence of illegally copying and distributing our intellectual property.
First, I would refer to your university that your research was conducted using illegal obtained materials: that is undoubtedly in breach of your contract with the university and I would press for the cancellation of your degree. Harsh? Yes, but you are a criminal benefiting from the knowledge, expertise and labours of others.
Secondly, I would take steps to have the site removed from major search engines and references to it blocked. We routinely do that now, when we become aware of them. We refer the site hosts to the relevant authorities in the countries where they are hosted with a view to having the site taken down and the owners / operators prosecuted.
We would publicise the internet host and its IP range with a view to responsible site owners blocking that host's customers from accessing websites around the world.
And finally, we would publicise your name and that you were prepared to use criminally sourced material for your own advancement, demonstrating both a tendency to criminality and that you operate in a moral vacuum, in the hope that no employer would engage a person with such a lack of ethical values.
If the book you want is not legally available on-line, go to a proper library where publishers and authors are rewarded for loans. See if the book is available for lending for Kindle (you pay a small membership fee) because, again, publishers and authors are paid when you borrow.
Would you thank the photocopy shop that makes illegal copies of text books?
No, because you know it's a crime.
