Encrypted instant messaging app Signal has tried to run a series of Instagram ads to show the amount of data the social media platform and its parent company Facebook collect about users and how it uses the data to push targeted ads. But that attempt was quickly shut down by Facebook, Signal said in a blog post.
Signal explained how it created some targeted ads featuring its own branding to illustrate that if an ad was being used to target a K-pop fan, it would say so. Or if the user was a teacher, it would also say so.
We created a multi-variant targeted ad designed to show you the personal data that Facebook collects about you and sells access to, Signal said.
