In 2011, Tunisians took to the streets against the ruling authoritarian regime. Catalysed by social media, the protests would reverberate around the world, spark the Arab Spring and lead to significant democratic reforms in the country. More recently, Tunisia’s democracy has reached a turning point. In 2021, as public frustration with the pandemic and the failing economy grew, the Tunisian President Kais Saied sacked the prime minister, suspended parliament and pushed through constitutional reforms consolidating his power. And now, it appears online debate is being suppressed. BBC Trending speaks to people who have experienced first hand how social media can be used to survey and attack the government’s critics.

"A flood of disinformation has erupted across social media in the online propaganda battle that’s being waged alongside the physical conflict between Israel and Hamas. Everything from video game clips falsely presented as genuine combat footage, to the outright denial of civilian deaths, have been deployed to try to skew the online narrative and warp public perceptions. BBC Verify’s Olga Robinson and Shayan Sardarizadeh examine the trends in this alternative war over the Middle East with the help of Eliot Higgins, founder of Bellingcat, the independent investigative organisation."

When an audio recording alleged to be from the Mayor of one of the world's largest cities started circulating online, reality was called into question. Mexico City's mayor, claimed the clip- which sounded like he was discussing a campaign against a political candidate- was AI generated. Others are convinced the audio is real. In this episode of Trending’s Power season, Jack Goodman and Laura García go on the hunt for answers. Using the latest AI detection tools, they explore the possibilities and limitations of verifying such content, and question how disinformation may shape Mexico's general election in June. Could AI disrupt elections around the world?

A BBC investigation has uncovered a network of fake social media accounts seemingly working together to promote the Ugandan government and the East African Crude Oil Pipeline. Online, an information battle appears to be going on – one being waged by hundreds of social media accounts set on pushing narratives in line with those of the Ugandan government. As part of a coordinated campaign, they have been artificially inflating support for EACOP online and viciously targeting those that oppose the project – both at home and abroad. But who is behind these accounts? And how influential have they become?

Over the summer, a mysterious Twitter persona published details of over 14,500 social media accounts - all of them controlled by real-life Serbian citizens, it's claimed. They stand accused of posting… whatever the President’s party tells them to. It’s long been rumoured that Serbia’s ruling SNS party commands the online activity of a small army of citizens, dubbed ‘bots’ by the opposition. But this kind of list, naming and shaming thousands of ordinary Serbians, is unprecedented. If true, their activity represents a form of political corruption according to Serbia’s public prosecutor. The government’s response has alarmed observers - it shrugged off the story, publishing instead a veiled tongue-in-cheek ‘admission’. But who is behind the list, and can it be trusted? BBC Trending has analysed the data in an attempt to establish if the ‘bots’ are indeed real people. And whether their accounts show evidence of co-ordinated activity. Featuring interviews gathered on the ground in Belgrade, we hear from opposition politicians, pro-democracy activists and a self-professed real-life ‘bot’. She tells us she trolled the President’s opponents under threat of losing her job – as a receptionist at a state-controlled electricity company in a small Serbian town.

Videos taken across India are going viral on social media. They show hordes of men harassing and even attacking young couples in the street. The clips are accompanied by a hashtag #BhagwaLoveTrap - and have been inspired by an inflammatory narrative. The theory suggests Hindu men are trying to seduce Muslim women and lure them away from their communities - but there’s scant evidence to support the idea. Shruti Menon meets the Muslim activists pushing the idea of a ‘Bhagwa Love Trap’, and asks what’s behind it. And she hears from a Hindu leader who thinks the theory is nonsense, and claims the reverse is happening instead. Presenter: Shruti Menon Producer: Sam Judah Editor: Flora Carmichael
