David Batty at The Guardian has an interesting piece about using social media to bust rich deadbeats:
Hall, a former lawyer turned corporate investigator, said most investigations were more complex, and involved using social media to map a target’s family and business networks. For example, they might use the metadata embedded in an Instagram post to identify their location, or use a Facebook “like” or tag to track down a proxy company. He said: “You can start building up a profile of that individual: where they are; what their interests are; who are they regularly in touch with?”
Anyway, it's just meta data, right?
