The hackers group Anonymous released the names of hundreds of people they say are members of the white supremacist Ku Klux Klan. It comes after a public relations campaign by Anonymous conducted mostly on social media. But what happens when hackers get it wrong? BBC Trending speaks to a woman who got caught up in the online war who says she was falsely labelled as a KKK sympathiser.

We also look at what happened in Brazil after a 12-year-old contestant on cooking competition Masterchef Junior was harassed online. The incident prompted feminist Juliana de Faria to create a campaign for women to share their first experiences of sexual harassment. Thousands of women joined the debate and shared their stories online.
