Ahead of Kenya’s general election, a bitter war for public opinion was being fought on social media. In a bid to sway the result, online influencers – from students to pop stars – were offered cash in exchange for political messages. Critics say that paid political messages are swamping social media – but they aren’t declared as adverts, and instead they pose as genuine political opinion. We meet some of the key players in the country’s online information economy:

MrBeast is YouTube royalty: with more than 100 million subscribers, he has legions of fans around the world, in awe of his elaborate stunts. He is one of the highest-paid stars on the platform - and yet, the American YouTuber says he wants to use his platform to “make the world a better place”. He has thrown his weight behind two viral environmental campaigns: #TeamTrees and #TeamSeas. Together, they have raised more than 55 million dollars to plant trees and remove plastic from the ocean. MrBeast’s supporters say he has energised a “new generation” of climate activists, but some experts have doubts: they have questioned how much of a difference these campaigns will actually make. Do they have a point?

How did a bizarre US-based conspiracy theory about Donald Trump being the saviour of the world, lead to people protesting in the streets of Tokyo and Osaka accusing police of being reptiles? From its obscure online beginnings only a few years ago, the QAnon movement in Japan has morphed through several different phases, becoming ever more extreme in the process.

Its latest incarnation is a group called Yamato Q, which embraces a series of wild and false claims. Its members believe they have different genes from the rest of the population and that Covid-19 does not exist. Some have even attempted to disrupt vaccination centres. So should wider society be concerned?

Romana Didulo is a QAnon influencer who proclaimed herself “Queen of Canada”. She has issued a series of bizarre and bloodcurdling “royal decrees” claiming to have cancelled all personal debt and threatening the death penalty for those who defy her. It’s all a complete fantasy, but that hasn’t prevented her attracting a sizeable following which helps fund her tours around her kingdom in a fleet of large motor homes. Now this maple leaf monarch is seeking to expand her empire beyond Canada. But all is not well in the court of Queen Romana. Followers who believed her claims are suffering the real life consequences of stopping paying their rent and utility bills. While others who tried to enact her commands have faced arrest.

Russian QAnon and the Ukraine dilemma QAnon is rooted in the deep divisions of American politics and helped inspire the storming of the US capitol in Washington. So why has this bizarre and baseless conspiracy theory also been attracting supporters in places like Moscow and Siberia? The third part of Trending’s mini-series about the global impact of QAnon investigates its growing popularity in Russia. But while some supporters have adapted QAnon ideas for a Russian context, this fledgling movement has now been thrown into disarray by the war in Ukraine.

What happened when a bizarre US-based conspiracy theory surfaced a continent away in Africa?

In the second part of Trending’s mini series about the impact of QAnon around the world, we report from South Africa.

At the heart of QAnon is the baseless claim that former US president Donald Trump is waging a secret war against a cabal of powerful paedophiles who run American politics and Hollywood.

But in South Africa, elements of QAnon have been translated into the local context of pre-existing tensions in society, and are helping turn South Africans against both immigrants and one another.

Believers in the QAnon conspiracy theory were part of the mob that stormed the US Capitol on 6 January 2021. Even though the movement’s figurehead went silent for months, followers continue to try to influence American politics – but their tactics have changed. Members of a coalition assembled by a QAnon influencer are running for public office in more than a dozen states, targeting positions that control elections. Among them are Jim Marchant, a Republican candidate for secretary of state of Nevada, and Doug Mastriano, who won a fierce primary battle to win the Republican nomination for governor of Pennsylvania. They’re both part of the America First Secretary of State (SOS) Coalition, a group that was founded by a mysterious QAnon influencer who operates under the pseudonym “Juan O Savin”.

A new extremist Hindu movement made up mostly of young men is emerging in India. They call themselves “trads” – short for traditionalists - and they mimic the tricks and techniques used by the American alt-right.

It is hard not to feel anxious about climate change. After all, the world is already experiencing the effects of global warming - and scientists tell us much worse could still be on its way.

For some, tackling climate change feels like a lost cause: a job so big and complex, that it is doomed for failure - the demise of the human species is inevitable. This is wrong. But even though this view is predicated on falsehoods and distortions, it appears to be spreading online - and a lot of young people are getting sucked in. Why is "doomism" going viral? And who are the activists and campaigners standing up to it?

Brazilian president Jair Bolsonaro has enjoyed a particularly close relationship with the gaming community. They were one of the groups he relied on to get elected in 2018 and he has since rewarded them by lowering taxes on video games consoles.

The country’s gaming industry is unique – forged by a combination of strict import laws under military rule, homegrown talent and later, high prices which kept the world of gaming firmly in the hands of the rich and privileged.

Brazilian gamers were drawn to President Bolsonaro’s straight talk. But there are hints that things might be changing. His handling of the coronavirus pandemic has caused Bolsonaro’s approval rates to fall across society – and gamers are no exception. Some high profile gaming supporters have turned their back on the president. Plus the industry’s demographics are rapidly shifting, and not in Bolsonaro’s favour. So how are video game developers visualising the 2022 election? And can President Bolsonaro still rely on the support of the button bashers to defeat his arch enemy Lula?
