I guess another important part is that it's the universities' connection that scihub 'uploaders' tunnel through that are key - they have the special network access to DOI resources that make it free for on-site university users to get anything for free, and then the 'uploaders' relay them to outsiders. That's a difference between papers and something like 'scihub for any pdf ebook via ISBN' - there's no special network that can get all ebooks for free just via ISBN - except maybe the Library of Congress ;)

> I guess another important part is that it's the universities' connection that scihub 'uploaders' tunnel through that are key Does this happen in realtime? I read that sci-hub sometimes uses credentials from legitimate users, but in that case they would be easily identified. So, perhaps someone with access submits papers on request? And if so, what about watermarking?

  Plenty of the papers I've gotten from scihub are watermarked. The "downloaded by [IP] at [timestamp]" footer could probably be stripped, but they don't appear to do so, or at least not consistently.
