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?

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.

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.

In Malaysian Borneo, indigenous people have struggled for land rights against companies and the state.

In this episode of Trending we’ll be exploring how technology and social media are being used and misused to shift the balance of power.

"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."
