No news on why, he just vanished. He changed his name a few times (last one was user18081971 , his date of birth), then apparently posted something about Antartica (not sure about that), then it was gone. Every name he used throughout the event was copped by trolls. That was it. No news about the next step.
Maybe it was pressure from 'suits', that could also explain why he didn't make the last batch downloadable (as a compromise maybe).
Yeah, he posted those coordinates to a hole in Antarctica for his 'location' on soundcloud. When I refreshed the page it was gone. Then someone saw a comment (but I can't confirm) that was essentially, 'perfect opportunity to promote my shit knock-offs'. Then that was it...
