It was posted about a month or two ago. I didn't have it backed up when I needed to wipe my machine.
It was an Opsec Slide Show for hackers, not targeted at the DNM community. It included many tips and rules and conversations between Sabu and feds, and Sabu and his accomplices, giving lessons as to not what to do.
I liked that information, and would like to add it to my personal back up library
