Journalists Harriet Robinson and Andy Howard used fictional profiles as part of a week-long investigation into how teenagers might see harmful content online.

This is the response from social media companies here.

Deputy Chief Constable Katy-Barrow Grint of Gloucestershire Constabulary is in our studio talking to BBC Points West presenter Amanda Parr about whether teenagers should, or shouldn't, be considered as victims of domestic violence.

And David Wright, chief executive officer of online safety charity SWGfL, tells Amanda manufacturers need to make it easier for parents to monitor phones.

Much of the discussion around online safety focuses on teenagers, but younger children often go online to watch videos or for gaming.

There is a huge range of resources aimed at primary school children available on BBC Bitesize here.

Earlier this week, we reported how a mum has started a campaign to highlight the danger of phones for young people as pupils get ready to take exams.

Miranda Wilson, from Bath, set up Teched Off to raise awareness of the dangers of social media and smartphones for young people.

She said: "What I would like is really simple; one is legislation to stop under-16s being on smartphones and social media and two is a public health campaign so parents are educated about the harms."

At a discussion event in Bath this week, she screened a film about the dangers of smartphones for children, featuring interviews with health professions who are part of the group Health Professionals for Safer Screens.

Dr Rebecca Foljambe, founder of the group, said children are dealing with issues like "very poor sleep" and body image concerns.

Twelve-year-old Louis, a student at Bournside School in Cheltenham, said he had been "spending a lot more time playing games and football with my brother" after cutting his smartphone use over the past month.

He told us he would usually be on his phone "before and after school", mainly to play games and watch videos but said "frightening videos did keep coming up" on certain apps.

Faith, 12, said she has been "spending more time with family" and "becoming less reliant on screen time" since going smartphone-free.

Benjamin, 11, said he used to watch YouTube regularly, but when his mum took it off his phone he said it was the "first night he spent hours outside in the garden with his sister".

"I've noticed I'm doing so much more outside and my sleeping patterns are better," said Jemima, 13.

Staff at Bournside School in Cheltenham are encouraging pupils to go smartphone free until at least Year 10.

Find out how they are getting on in this clip above.

Pupils at King's Oak Academy in South Gloucestershire spoke to BBC Points West presenter Amanda Parr about online safety.

Student Lillie told her she would like parents to help educate them in online safety.

She said: "When you're not told what to do, how are you supposed to be expected to know what to do? If you're a parent and you're going to let your children have a phone and be online, you need to take on that responsibility and educate them, and lay down the rules."

Karl Hopwood is an independent e-safety expert and works with the network of Safer Internet Centres across Europe.

He told the BBC that social media can be a positive place to "communicate and learn", but that young people can be exposed to "very challenging content on subjects such as suicide, self-harm and eating disorders".

He said sextortion scams (blackmailing people when they have shared explicit images) was becoming more widespread on mainstream social media platforms.

"There's a lot to be concerned about."

He said the most powerful tool was talking to young people: "We would want young people to come and tell us when things go wrong. In reality, they fear the reaction of their parents... their parents will ask where that happened and the parents will say 'well you can't use that then'.

"We need to think carefully about how we react, otherwise they won't come and tell us when they need ."

He said for older teens, talking to them about their online reputation affecting job and university applications, or visas for visiting the United States, can be "quite powerful".

He advised parents to use s, external [external website] to help safeguard young people.

Earlier this week Gloucestershire reporter Georgia Stone met staff and students at Bournside School in Cheltenham, which is on a mission to delay children getting smartphones until at least Year 10.

School rules mean all phones have to be turned off and put away within school hours but teachers want to encourage less screen time at home too.

Throughout the day we've been sharing details of our investigation into what teenagers are being shown on their social media feeds.

Reporters Harriet and Andy spent a week posing as six different teenagers, all from the West, who had interests ranging from Sabrina Carpenter to Call of Duty, and simply scrolled for ten minutes a day on each of their Instagram, TikTok and YouTube feeds.

But while their viewing was initially largely related to their interests, troubling and potentially harmful material began to appear on their feeds - including posts apparently referring to suicide, poor mental health and violence.

The following are screenshots we gathered throughout the course of our investigation:
