Caution: even looking for most sites on the black net will be hazardous to everyone you know!
The dark underbelly of the Known Net, where 'black ops, blacker technology, and blackest death'. take place or can be had. Many nodes and networks within it are often suspected to be tools, or weapons of the Solipsist Panvirtuality. There are transapient, hyperturing, and high toposophic level subroutines running there that will warp your mind and eat your soul. Whole worlds have died or been driven mad by carelessly accessing information from the 'Net. Enter at your own risk.
