Instagram is listening to you Anonymous 08/26/2017 (Sat) 21:44:37 No. 10897 del

Interesting. I've noticed this too when I see a friend connect to his facebook while we are working. Sometimes I talk about a random subject and minutes later facebook shows an ad about this uncorrelated data.
I don't think they are actually using microphone, but I think it's almost certain that they correlate the data/metadata about the users with such precision, at the point to build a oracle sybil ad system.
Can anyone here understand how this is very dangerous? They can control everything using this.
