This episode is all about bots on social media with guest Samuel Woolley, Director of Research of the Computational Propaganda Project at the Oxford Internet Institute at the University of Oxford. We discuss exactly how users make bots, and the ways they are deployed on Facebook and Twitter to influence politics through, for example, spreading fake news or disrupting protests. Sam explains how bots are difficult to trace, since they are often geotagged in misleading locations or used for digital marketing. We also talk about bots in the latest 2016 US Presidential campaign between Donald Trump and Hillary Clinton, as well look forward a bit into how bots might evolve in the future.
