They spread like wildfire, but where do they come from? This week, the world of memes. What goes viral online might seem random, but memes can be engineered and hacked to carry political messages. Trending talks to Gianluca Stringhini, associate professor at University College London. His team has been looking into fringe internet groups – they’ve found that some far-right websites and message boards have a disproportionate impact on the memes that spread on mainstream social networks.

The booming global gaming industry is dominated by young people. But five pensioners who call themselves the “Silver Snipers”are proof of gaming’s wider appeal. Trending follows the team as they head to DreamHack, a professional eSports tournament in Sweden.

They’re keen to shoot their virtual enemies, and they have plenty of young fans, but can the Silver Snipers take down their arch rivals from Finland, the Grey Gunners?

It was one short tweet. A transgender activist Miranda Yardley called another transgender activist, Aimee Challenor, a “man”. It certainly wasn’t the first controversial or potentially offensive remark that Miranda Yardley had tweeted out, but it does appear that it was the final straw for Twitter, which handed her a permanent ban. While Miranda says that her views should be protected under the principle of free speech, Aimee says the tweet - and other comments posted online - were part of a long pattern of bullying and harassment. Trending explores the complicated political world of transgender activism and how philosophical battles within transgender communities are playing out on social media.Presenter: Lee Kumutat Reporter: Mike Wendling(Photo: Illustration of people going from woman to man Credit: Getty Images)

Who is “Philip Cross”? That’s the name on an account that has made more than 130,000 Wikipedia edits since 2004. But it’s not so much the volume of his work but his subject matter that has irritated anti-war politicians and journalists around the world. His detractors claim that he’s biased against them and that his influence has made some entries unreliable. It’s a charge that’s rejected by the foundation behind Wikipedia, but the person behind Philip Cross remains elusive. So what happened when we tried to track him down?Presenters: Lee Kumutat, Jonathan Griffin Studio Manager: Mike Woolley Picture Caption: Screenshot of the online encyclopaedia Wikipedia, one of the world’s most popular websites.

Anna Scanlon made videos about her vegan lifestyle. It was a good way to build connections and keep in touch with people from back home. But one day she angered a fellow vegan blogger. What happened next was, she says, a nightmarish scenario in which she became a target for abuse and unfounded rumours. She was even accused of performing sex acts on camera. She appealed to social media companies but got little response. And now she has filed a lawsuit which is about to lead to a trial – and which might have big implications when it comes to defamation online.
