Per Rule 3.6: No distribution or solicitation of pirated books.

We aren't telling you not to discuss piracy (it is an important topic), but we do not allow anyone to share links and info on where to find pirated copies. This rule comes from no personal opinion of the mods' regarding piracy, but because /r/books is an open, community-driven forum and it is important for us to abide the wishes of the publishing industry.
