Luckily much of what we see on social media is safe. But somewhere, somebody has to watch all the horrific content uploaded online in order to filter it out for the general public. We speak to a former moderator who worked on Meta platforms in Ghana. Plus, the community project in Puerto Rico with an innovative way of keeping its power on. And we say goodbye to video call program Skype. (Warning – this episode includes some distressing content and a reference to suicide.)
