John Oliver shows how innocent people's lives can be destroyed by unwarranted public shaming. As an example, he gives the example of the woman who "sued her nephew" for injuring her by hugging her too hard. The real story is more complicated – the woman was forced to sue her nephew to get the insurance company to pay her bills (and her nephew and her parents were happy about it). As a result of the public shaming online, no one would hire her, and she had to change her identity.
He also interviewed Monica Lewinsky about her thoughts on public shaming, having been a victim of it for years.
