Video Nasty & Snuff Film Documentary

Here's an episode I've found of a British documentary series about video nasties and snuff films.
The name of the series is "The Dark Side of Porn".
The episode is called "Does Snuff Exist?".
Here's a link to watch the full episode.

I snatched this series from demonoid a while ago when I was looking for a copy of Debbie Does Dallas. Maybe now I'll actually watch it.

I have not watched the documentary yet. But does a snuff film HAVE to be commercial in order to be considered so? If not, well, there is now at least 1 known snuff film, released on the internet around the day this thread was made.

I have seen it, like quite a few people now, it's surprisingly easy to find. It is extremely disturbing at best, (Brad review voice) but the soundtrack was great.

Edit: Documentary answered my question.
