Adam Joinson explores the positive power of online anonymity on BBC Radio 4

19 August 2026

Professor Adam Joinson, Director of the Institute for Digital Security and Behaviour, has contributed to a BBC Radio 4 Sideways episode exploring the power of strangers to make a difference.

The Stranger tells the story of mental health campaigner Ben West, who lost his younger brother Sam to suicide in 2018. Ben has since channelled his experience into campaigning for better mental health support and created Reasons to Stay, a suicide prevention project connecting people with anonymous letters written by strangers offering warmth, hope and connection.

The programme explores how a message from someone you have never met can provide an important moment of connection and interruption when someone is experiencing suicidal thoughts.

Adam discusses the distinctive effects of anonymity online. While anonymity can sometimes contribute to negative behaviour such as aggression and “flaming”, he highlights its potential to encourage greater openness and self-disclosure – helping people form meaningful connections with others.

He also points to the positive communities that exist online, including forums and support networks where strangers offer advice, care and understanding.

As Adam highlights, the conversation about online behaviour can focus heavily on toxicity. But digital spaces can also enable people to connect, share deeply personal experiences and support one another.

Listen to The Stranger on BBC Radio 4's Sideways.
