A hacker named Gabriel aka “go harry” claims to have hacked into the computers of Bloomsbury Publishing, the publisher of the Harry Potter books.

He posted plot spoilers which happens near the end of the story on the insecure.org site. He also posted why he did the exploit:

We did it by following the precious words of the great Pope Benedict XVI when he still was Cardinal Josepth [sic] Ratzinger.
He explained why Harry Potter bring the youngs of our earth to Neo Paganism faith.

So we make this spoiler to make reading of the upcoming book useless and boring

He claimed to have gotten access to a draft of the transcript by sending an email-borne threat to employees at Bloomsbury.
