To start off I seek anonymity so I'd really have to stick to Tor. And the files that are pirated are mainly a range of PDFs and DJVUs of books, articles, magazines, ... that I collected over several years.
As someone who travels a lot and who wants peace of mind, it would be really great if I can have that entire data placed online (most of it would still be in place in Scihub but who can guarantee that?), and to be specific: if I want to read book X all I have to do is to go to a link associated with it and that loads the PDF in the built-in PDF reader of my browser, or it will be downloaded in case it's a DJVU. But in that case one can't guarantee either that such data won't be taken down after a DMCA takedown notice from Elsevier&co, and even if one saves it with the Wayback Machine then the Internet Archive will have to comply with the DMCA takedown notice (In fact saving it there may make it even easier for crawlers to find). For example Github is a really good example of a place where things like this may happen.
So my basic question is does anyone know some site or service that can suit my use case? It could be something based on a decentralized protocol, I don't know, as long as it can be accessed from the Tor Browser. (There's I2P which works fantastic with torrents and is anonymous too but only a few people would be seeding your files in the first place and it doesn't fulfill the conditions in the 3rd paragraph :( )
