The concept of "sexual interference with a human corpse" is curious. All a corpse can do on its own is decay, so the only possible "interference" is to prevent its decay. Thus, "sexual interference" rationally would mean some sexual activity while injecting embalming fluid, or while putting the corpse into a refrigerator. However, I doubt that the censors interpret this term rationally. They will have cooked up an excuse for some twisted interpretation that enables them to punish more people.
