What do you mean? At least the current URL [0] returns a response of content-type application/pdf. So the builtin pdf viewer of your browser should display it, no? I know sometimes admins change URLs tho.
Even so, I'm not interested in providing or generating something random. If the site doesn't want to work with someone who values privacy then I don't want to work with that site. :)
