NPD4n6: Nicks DFIR blog

Signal Messenger tried to post Instagram ads to showcase the level of granular data that Facebook has stored about its users – the ads included occupation, hobbies and recent life events of users, to name a few.

Facebook wasn’t too keen on this, so they blocked the ads. Most people don’t realise how much Facebook knows about them.
