Hello!
To start my attempt at not lurking I am posting a link to the collection of links I have from Reddit regarding various Piracy sites. Please keep in mind this is my personal collection. You should ABSOLUTELY vet the links yourself. I am just a guy on the internet, I am not a trusted source.
This is not a complete list. This is just the sites I refer to for their specific category. I've omitted a fair bit too since the megathreads / link collections have them already too.
for books, IRC is a very good source. you can use use this guide to download stuff just make sure to use hexchat instead of mIRC. I see you didn't include links for mobile apps, some good ones are, moddedcentral on telegram, mobilism and filecr (also has PC apps), 4pda is also good if you can manage to make an account there 😅
Thanks! I will add a mobile section. I specifically didn't because I honestly don't fully trust most of the links I have collected for mobile. I'll post those I at least trust.
