The 100th episode of Think Change returned to a question it first explored just days after Russia's full-scale invasion of Ukraine: how is disinformation shaping the way societies understand conflict and politics? Host Sara Pantuliano was joined by the BBC's chief international correspondent  Lyse Doucet, former UN diplomat Lord Mark Malloch-Brown, and LetsData co-founder Ksenia Iliuk to look at what has changed in the four years since.

Ksenia argued that while the core of influence operations remains unchanged — deceiving a target into doing or not doing something — the operational shape has changed fundamentally. In March 2022, Russia's influence machine still ran through centralised, Kremlin-controlled media outlets that the EU was slow to sanction. Four years on, those operations have decentralised into localised-looking online communities, bot networks, and synthetic identities — and they are no longer Moscow's alone. A growing market of disinformation-for-hire vendors and small private operators, enabled by AI, means "two guys with a laptop can now run an influence operation."
