Not sure what the links were but it might be about the makers of this film being accused of making a snuff film based largely on this impalement scene. From Wikipedia:
"To prove his innocence, Deodato had Luca Barbareschi get in contact with the other three actors, and the four of them were interviewed for an Italian television show. Deodato also explained in court how the special effect in the impalement scene was achieved: a bicycle seat was attached to the end of an iron pole, upon which the actress sat. She then held a short length of balsa wood in her mouth and looked skyward, thus giving the appearance of impalement. Deodato also provided the court with pictures of the girl interacting with the crew after the scene had been filmed. After they were presented with this evidence, the courts dropped all murder charges against Deodato."
Amazing. It's a powerful thing to see a human in that position, even if we know it's a movie. Incredible he was taken to court over it to prove it was all staged.
