The "consenting adult" material is not there for consenting adults. It is there to bury the illegal content and to numb the emotions of the viewers while viewing the illegal content. The depravity of the end result content (pedo, hebo, beast, torture, etc, etc getting darker and more evil as you go down the list, as if any of it was even a tiny bit acceptable to begin with) requires breaking the brains of the viewer to make them numb to the negative morality that they are participating in. There are many investigators that succumb to the content because of how it is crafted and the fact that our brains will just shut down to protect ourselves. Shutting down reduces the ability to make appropriate decisions, enhances the desire to see more (morbid curiosity, like watching a train wreck and seeing the deaths occur but not being able to look away while it is occurring) even though it is not something that you really desire and it destroys your ability to engage with other human beings without the dark lens you have been viewing through during the investigations.
