The fifth Harry Potter book is due out in June. But already the internet is flooded with fakes purporting to be the real thing. “There are quite a few fakes out there. It’s a growing problem because the internet is becoming more and more prevalent. We monitor it very closely. Sometimes they have JK’s name on it which is potentially very damaging. I find that quite annoying, we’ve got to take action. Sometimes they’re pornographic which is even more annoying because a lot of the fans are kids.”
