3.5 stars - Started off really well and I was all in but definitely tapered off. Public shaming, like the internet, is a moving beast, and having been published in 2015 this book is largely outdated now. 
I also thought the ending was a bit of a let down and didn't reach much of a conclusion.
I have a huge interest in cancel culture, the media and the internet. Though not unjoyable, this book was not as good, as well-written or thought-provoking what I thought it would be.
