A thought experiment. Consider the following:
Imagine that you were in a position of power and someone wanted to bribe you. Typically they would offer you money in exchange for favors. But what happens if two groups of people want to bribe you and you have to pick one over the other? They enter a bidding war. At a certain point the money gets so high that it loses all value. So what happens then? What if you simply couldn't be bought?
Then they would have to kill you and make a deal with your replacement.
What if you weren't afraid of death? They would threaten your family. To save someone you love, lets say, you agree to take the bribe.
How do they insure your compliance? Blackmail?
What sort of blackmail would work? Letterman had an affair and they tried to blackmail him. He called their bluff.
So the blackmail has to be something really nasty. Something that would destroy you if it got out. You've just created an evolutionary force that would create the absolute dirtiest blackmail possible.
By definition, blackmail must be the worst thing imaginable and culturally specific.
You would therefore expect to find the people with the most power being susceptible to the worst forms of blackmail.
How to identify it? It would need to be so unimaginable that even if it got out no one would believe it.
We have people who make claims about the rich and powerful that no one believes. In South Korea a group of 8 women brain washing the prime minister - grooming her from birth.
In America, a satanic cult of pedophile cannibals.
Of course, no one would ever agree to do something like that. Not at first. So you spread nets. For satanism you have a public face of wiccans doing politically correct forms of magic. Wiji boards, tarot cards, voodoo dolls. People interested in those subjects get deeper and deeper into the occult looking for the next big thrill. They are groomed just like the South Korean prime minister.
Imagine a fraternity, say skull and bones, something the children of the elite want to join for power. You make them engage in homosexuality. You break them down by making them sit in a bathtub of feces while men piss on them. You have them sleep in a coffin. You get the idea.
Fuck this gay earth.
