You could also add the various other efforts in Open Access domain that were linked on this page to your http://thepaperbay.com/others/ page. There was at least Pirate University, articleak, and /r/scholar.
Also, while it's okay to have a somewhat complexe form to fill when making a request, it's really sad that it's as much work to share a paper, it should be very easy, in particular when clicking "I have this, send it", the form should have only one field: the file upload, or at least have the other prefilled with the request's values.
At articleak (see my other comment), we only ask for the link to the paywall, and then if we could not get it from there (we make the http request via Tor for obvious reasons so it may fail some times) we ask you for the title of the paper, and that's all. So in the worst case you have to fill in two fields, but in most case, only one: the link to the paywall.
However, I would not be as hard as you seem to be with the pirate would made The Paper Bay. When you really need a paper and you already lost half an hour searching for it in the web ocean, it's okay to take 2 more minutes instead of 30 seconds to ask for it on such a service.
I submitted articleak, which something very similar a few days ago, but it didn't get upvoted. Maybe people on Hacker News do not like Tor?
The idea of using Tor is that the site is way harder for authorities to get down, and even if they do break Tor and get to the server, the users will still be entirely protected (there can't be any information about them in the logs or anything).
