YouTube comments are the third worst place in the universe (just behind Newt Gingrich's bedroom and IMDB comments). Here's how one YouTuber deals with it.
I've gotten a lot of internet hate in my time. I've gotten death threats - plausible and otherwise - I've gotten nasty comments, I've gotten sneering nastiness. But none of it really compares to the extraordinarily vile shit that gets plastered in the comments on YouTube. I mean, it's like an unplugged sewer of hate - sexism, homophobia, racism, general misanthropy. It makes the Ain't It Cool talkbacks look like a Parisian salon of the 17th century.
This video is a very funny, very well-done response to those trolls. It's filled with what I suppose are big time UK YouTube people (there's a whole alternate culture on YouTube, filled with people you've never heard of who have millions of followers) reading off some of the best comments they've had. It's also quite a catchy tune.
