We find out why trolling has become as much a feature of the internet as videos of cute kittens. Author Jon Ronson, who has just published his latest book So You've Been Publicly Shamed, tells us about people who have suffered persistent online abuse and gives advice on what to do if you become the target of trolls.

Also, the 大象传媒's economics correspondent Robert Peston speaks about his experience of being abused online and how he dealt with it. Plus, we get a profile of who is likely to engage in trolling from London-based psychotherapist Dr Aaron Balick, while Claire Hardaker, linguisitics professor at Lancaster University, assesses whether Twitter's latest attempt to clamp down on online abuse is likely to be effective.
