Signal exposes Facebook user data collection through Instagram ads

Today it became known about the action launched by the team of the Signal messenger. The company launched targeted ads on Instagram with many different ads that shared personal information about users. This was done in order to show what data Facebook collects about its audience.

Ultimately, each user saw the basic information about himself that the social network collects and sells access to it. Thus, people could see data about their work, geolocation, personal interests and even relationships.

As Signal says in its press release, “Facebook’s own tools can reveal things about you that no one else can. However, in the ads that appears to users; you can already see that strangers know even more about you than you do. We wanted to use the same tools to show directly how this technology works and just bought an Instagram ad”.

For example, one of the ads looks like this: “You came across this ad because you are a chemical engineer and love K-pop. This advertisement analyzes your location and sees that you are in Berlin. Your child was recently born and you have moved. You’ve been doing a lot of exercise for pregnant women lately”.
