Fighters from dissident armed groups in Colombia are using TikTok to glorify their lives as guerrillas and recruit youngsters. These armed groups didn't like the terms of a peace treaty negotiated between the Revolutionary Armed Forces of Colombia (FARC) and the government in 2016, and they kept fighting against the Colombian government. These groups make their money from illegal businesses. Their videos have struck a chord with teens, particularly in rural areas like the Cauca region in west Colombia. Although not all the videos actively offer jobs, there are hundreds showing off what they portray as a slice of life inside the guerrilla: money, cars, guns, women, community and purpose. They do not emphasise the dangers associated with the lifestyle. So how popular are these TikToks and what does it mean for Colombia that there’s tonnes of them, easily found by young people with smartphones across the country?

Jusper Machogu is a farmer from southwestern Kenya who describes himself as a “climate sceptic”: he wrongly claims that climate change is a “scam” or a “hoax” designed to hold Africa back. On social media, he has also become known as a staunch defender of fossil fuel exploration in Africa. His views have caught the eye of those in the West who, like him, deny the overwhelming scientific consensus on global warming. They have helped him grow his following and spread his message globally. But, in doing so, has Mr Machogu unwittingly become a tool for the fossil fuel industry? And, on a rapidly warming planet, just how dangerous is the message of social media influencers like him? Presenter/producer: Marco Silva Editor: Flora Carmichael

Farmers' protests have been erupting across Europe, and on February 20th one image from a protest in Poland went viral. It showed a tractor carrying a soviet flag and bearing a slogan calling on Russian President Vladimir Putin to ‘bring order to Ukraine, Brussels and our rulers.’ The man driving the tractor was arrested and is currently awaiting trial. After the image was released Poland’s foreign ministry spokesperson released a statement warning of attempts to take over the country’s agricultural protest movement by extreme and irresponsible groups ‘possibly under the influence of Russian agents.’ In this episode of BBC Trending, we attempt to track down the man behind the banner. Who is he? And what’s the evidence for Russian involvement in, or amplification of, farmers’ protests in Poland and beyond?

In a viral thread posted on X in January this year, a 23-year-old Russian man claims he used ChatGPT to filter through and chat thousands of women on Tinder, eventually proposing to one that was selected by the algorithm. The scale and success of his experiment sparked scepticism. Some raised doubts about the technical plausibility of it, while others voiced concerns about the ethical implications of such an endeavour. In an attempt to better understand his experiment, BBC Trending interviewed the Russian man and asked experts what they made of it. As AI becomes more advanced and accessible, the story also highlights broader concerns about the future of this technology in online dating. How will AI reshape the landscape of online dating in the coming years? What biases may be inherent in its algorithms? Is using AI in this manner a form of catfishing?

Long Covid can ruin lives, and scientists are striving to understand the condition and beginning to get some early clues about possible treatments. While there are still more questions than answers, though, many have turned online for help. But could what they find there sometimes do more harm than good? Rachel Schraer goes undercover to investigate the Lightning Process, a controversial treatment programme being promoted online for Long Covid. Reporter: Rachel Schraer Producer: Paul Grant Editor: Flora Carmichael

In 2024 yet another Kennedy is making a bid for the White House. Robert F Kennedy Jr - nephew of the late President John F Kennedy - is enjoying strong polling numbers for an independent candidate. He’s running on a platform of promising to take on powerful vested interests to create a better life for the average American. But away from his Camelot-infused stump speeches, he is facing questions about his long and controversial record of spreading misinformation about the safety of vaccines. In this episode, the BBC’s Health and Disinformation Reporter Rachel Schraer investigates how Kennedy is building a base from across the political spectrum, inspite of, or because of, his views on public health policy.

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.

Earlier in October, Australia took to the polls in a referendum and rejected the establishment of an indigenous advisory body in the constitution - the Voice. Beyond the typical controversies, social media became flooded with false information. In this episode of Trending, we’ll delve into how online conspiracy groups garnered support for their extreme theories to oppose the Voice, and gained unlikely allies along the way. Presenter: Beth Godwin Reporter: Jacqui Wakefield Producers: Jacqui Wakefield and Beth Godwin

A life coaching group has been accused of trolling former members. Lighthouse International Group promises to help people realise their dreams and ambitions, but the reality is more sinister.

BBC Trending's series Trolled lifts the lid on online abuse and trolling on and off social media. Presenter: Catrin Nye Producer: Ed Main Editor: Flora Carmichael

Mike Wendling and Maxine Hughes explore how extreme conspiracies and right wing rhetoric went mainstream in America. From the Proud Boys' Enrique Tarrio, to far right militias and Antifa, we hear from individuals on the extremes of American politics about what they believe and why, and explore what part social media has played in the radicalisation of parts of American society. Presenter: Mike Wendling Reporter: Maxine Hughes Producer: Kayleen Devlin Editor: Flora Carmichael

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

TikTok started as an app for posting lip syncs and dance videos, but quickly developed into a platform where users can follow along world events, criminal investigations and social unrest in real time. From frenzied speculation over true crime to vandalism and protests at schools, TikTok seems to be connected to harmful behaviour offline as the app draws in billions of eyeballs and spawns all kinds of content out at scale and speed. According to several company insiders, TikTok’s drive towards participation and maximising engagement has led to these frenzies. TikTok says their platform isn’t to blame, but is the app changing our behaviour? Presenter: Marianna Spring Producers: Beth Godwin and Olivia Lace-Evans Editor: Flora Carmichael
