I came across it years ago, there was a recommendation from someone who had liked the ‘Sara is missing’ type apps.
It was basically about the ‘disappearance’ of a young woman, and you had to search her Twitter/her friends Twitter to see if you could figure out how she went missing, by looking at the interactions between them/pics posted etc.
I feel like it had something to do with the BBC but I might be imagining that part.
I had a lot going on at the time, and completely forgot about it, but it’s just randomly popped into my head.
I’ve tried googling, but I’m only coming up with actual stores about missing people.
As far as I remember the main character/girl who went missing was a young mixed race woman, who had pics etc up on Twitter, you had access to her Twitter plus all her ‘friends’ and could navigate through them to look for clues.
Maybe the whole thing has been deleted or something, but i can’t find any references to it, and don’t know what terms to use to look!
Any help appreciated, thanks!
