For example, he says one of his friends became drawn into content from a controversial influencer - and started to adopt misogynistic views.His friend “took it too far”, Cai says. “He started saying things about women. It’s like you have to give your friend a reality check.”

Cai says he has commented on posts to say that he doesn’t like them, and when he has accidentally liked videos, he has tried to undo it, hoping it will reset the algorithms. But he says he has ended up with more videos taking over his feeds.So, how do TikTok’s algorithms actually work?According to Andrew Kaung, the algorithms' fuel is engagement, regardless of whether the engagement is positive or negative. That could explain in part why Cai’s efforts to manipulate the algorithms weren’t working.

The first step for users is to specify some likes and interests when they sign up. Andrew says some of the content initially served up by the algorithms to, say, a 16-year-old, is based on the preferences they give and the preferences of other users of a similar age in a similar location.According to TikTok, the algorithms are not informed by a user’s gender. But Andrew says the interests teenagers express when they sign up often have the effect of dividing them up along gender lines.

The former TikTok employee says some 16-year-old boys could be exposed to violent content “right away”, because other teenage users with similar preferences have expressed an interest in this type of content - even if that just means spending more time on a video that grabs their attention for that little bit longer.

The interests indicated by many teenage girls in profiles he examined - “pop singers, songs, make-up” - meant they were not recommended this violent content, he says."It’s just awful and the smell is disgusting," she added.

Others were keen to highlight that Port Talbot’s story is not just one of steel.Iona Walker-Hunt, 17, hopes that the next time the media come to the town "it’s for a film festival – not steel".

"A lot of people think Port Talbot is just the steelworkers, but it’s not. There’s so much more,” said Ms Walker-Hunt, whose dad Nigel is an ex-steelworker who started his own business after being made redundant in 2015."Obviously it’s sad for everyone losing their job, but I also think it’s an opportunity to start something new and start a better name for the town," she said.
