Hello, you're about to listen to a BBC podcast, so I'd like to tell you where you'll find more just like it.

I'm Izzy Lee Poulton, an assistant commissioner for BBC Sounds, which means I'm involved in the whole podcast making process.

Whether that's developing fresh formats or facilitating eye-catching artwork, I helped project manage all the details that make our podcast stand out.

At the BBC, we've got access to storytellers and experts across a huge range of subjects.

It could be psychologists, comedians, celebrities or journalists.

No podcasts or day looks the same here.

So no matter what you like, check out BBC Sounds.

There's probably another podcast on there that you're absolutely love.

Welcome to TechLife from the BBC World Service, the programme about how technology impacts

all of us around the world. I'm Graham Fraser and this week we find out more about moderators,

the people cleaning up the internet, sometimes at a huge personal cost.

We'll have more on this in a moment.

Also in today's programme, we discover how developers are making games work for people with sight

loss.

If you add in a sound cue that says, oh, this is an attack I need to block, this is an attack

I need to dodge, that could make a game accessible to dodge. That could, you know, make a game

accessible in theory. And we meet the coastal rescue team in Scotland who have worked out how

to map fast-changing tidal flats. We've spoken before on TechLife about the people who work behind the scenes to filter out the worst content from ever reaching our screens on social media, the moderators.

Now, our technology editor Zoe Kleinman has been looking into this more closely

and spoke to the people who have done the job about the effect it's had on them.

She's made a documentary series called The Moderators and joins me now in the TechLife studio.

Hi Zoe. So tell us what is the program about and what do moderators have to do on a daily basis?
