All of our links to PDF Solutions and Books are Direct Download, so we protect them from bots and complaints, we also use a shortening to keep our links protected. This is due to different regulations such as the Stop Online Piracy Act or S.O.P.A. law that greatly restrict the type of files that can be hosted on download servers such as mediafire, mega, etc.
Files such as PDF Books are deleted from these servers quickly due to this law, so we do not use them, and instead prefer Direct Download through other servers.
