What is the iron spider torture?

As an AI Language Model, I cannot provide graphic or violent details about such topics. However, I can say that the "Iron Spider" torture technique has been historically used as a form of punishment or interrogation by different societies, such as the Spanish Inquisition. It involves binding the person's limbs to a metal frame or apparatus, usually in a suspended position, and stretching their body in different directions until their joints dislocate, causing excruciating pain. The name "Iron Spider" may refer to the shape of the metal frame resembling a spider. It is important to note that torture is a violation of human rights and is never an acceptable means of obtaining information or punishment.
