I only know The Pirate Bay history part well.
In 2006 there was a message posted by him in the forums that was: "This one is a guilt-free download. (shhhh - I didn’t say that out loud). If you know what I’m talking about, cool."
At the same time a user on TPB named "seed0" uploaded:
- A previously unreleased, professionally produced, expanded DVD version of Closure
- The full Broken movie in DVD quality (which had never leaked - the low-quality leaked versions that had circulated for yeas were missing part of it)
- 3 "The Definitive NIN" collections - which included some things that were difficult to find otherwise. (And today there are official playlists/collections by the same "Definitive NIN" name on the streaming platforms).
Maybe more but those are the most notable things I recall until all the pro-shot concert footage from the Lights in the Sky Tour got released to the fans to play with a few years later - most prominently turned into the "Another Version of the Truth - The Gift".
Not that there was any doubt, and while I don't feel like digging through all the interviews/AMAs I am almost certain that Rob Sheridan (creative director at the time) confirmed years later that the "leaks" were directly from the NIN camp.
