Early kid porn was associated with a green leaf. Nabakov wrote hidden secrets about his uncle who was a butt fucker and raped little Vlad as a kid. His uncle presented him with a green leaf.
Then early magazines with kids doing sex acts were called Green Leaf.
We did this in Pizzagate Voat three years ago. Maybe it is related to Evergreen?
