One other thing.. It may have been interesting to have brought up the infamous Something Awful photo the kick started the trolling. It was Chris's overblown reaction to that very innocuous and innocent photo, his over-the-top attempts to justify /defend himself and his public hissy fits that made him an Internet celebrity. It's because of this incident that I believe Chris brought most, if not all of the trolling, down on himself (just to clarify, I'm not saying that he "deserved" it, just trying to point out the cause and effect at work here). Sure, Chris may have still ended up being "discovered" at some point because he's a bizarre individual and he attracts attention, but things would probably never have escalated to the level they did.
I'm not suggesting that your documentary suffered because of this omission; on the contrary, I REALLY enjoyed it, I simply think that the above would have made an interesting addition.
