Chan Imageboard Lsm How Do I Find Hash Codes For Child Pornography?

How do I find Hash codes for child pornography? - chan imageboard lsm

I am running a website now a board to be more precise images, and I wonder where I get the hash values for many or all known images of child pornography.

The reason is that sites that I know Imageboard used to / still get huge dumps pornography (actually a protest against the new sites that people use in other * Chan), and we want to block the ability and people coined the car after these pictures.
