Prisons in Brisbane, Australia had a library purge about 15 years back. They wanted to remove anything that might excite a rapist or pedo. Among the volumes banned were Tom Sawyer and Oliver Twist.

What wasn't was a hardcover collection of "Romance Stories" which includes a story about a 12 year old raping his 9 year old sister, with no anatomical detail or the grooming process missing.

Censorship is always subjective, but really?
