Are you serious???? I remember the craze that Harry Potter was. For the last book, I was living in France at the time and books were printed in darkened rooms and escorted by security teams when leaving the facilities to avoid spoilers leaking. Not sure people realised it’s not a new thing. It’s completely unacceptable but it’s sadly happening all the time. Publishers and distributors should pull all stops because people can’t be trusted to be reasonable :( The authors suffer needlessly.
