I read So You've Been Publicly Shamed recently which detailed more stories like this. It should be required reading in every high school. The Internet mob is a cultural phenomenon of the current moment that we aren't going to look back on fondly.
To anyone that is interested in reading more about this, I recommend the book, So You've Been Publicly Shamed by Jon Ronson. It's an examination of public shaming with several modern examples and their consequences. He doesn't offer up any answers on it, but he approaches it as a curiosity and encourages us to think about it more. I quite enjoyed it back when I read it.
There's some good background info that Oliver doesn't mention but I wish it did in some form. See the book "So You've Been Publicly Shamed", EDIT: see TED talk about the book(thanks /u/foozledaa) , and see Justin Sacco's story especially. EDIT 2: Monica Lewinsky's TED talk briefly referenced in this segment is also worth a watch.
Public Shaming gets really bad because there is a very low bar for what counts as being worthy of being shamed, not to mention the sheer misinformation and circlejerks that can occur.
FWIW, MacFarlane claims that this episode was written
"a year and a half ago" (before "Nosedive" aired),
after he had read a book by Jon Ronson titled
So You've Been Publicly Shamed .
Seth Macfarlane supposedly wrote this episode after reading this book So you've been publicly shamed Plus the quote "I think you’re confusing opinion with knowledge."
Pretty much nails Reddit and the whole group think/hive mind.
> I just assumed Seth had binged watched Black Mirror shortly before writing 'Majority Rule.'
Or maybe he had read this book:
