Signal reveals Instagram ads Facebook didn’t allow it to run

Facebook has refused to run an ad campaign by Signal on Instagram. The ad campaign, which featured a series of posts, would have revealed what kind of data Instagram and Facebook gathered and used for targeted advertisements, according to Signal.

In a blog post titled ‘The Instagram ads Facebook won’t show you’, Signal revealed it had created a “multi-variant” targeted advertisement that would show users the personal data that Facebook gathered and sold to advertisers.

“However, Facebook’s own tools have the potential to divulge what is otherwise unseen. It’s already possible to catch fragments of these truths in the ads you’re shown; they are glimmers that reflect the world of a surveilling stranger who knows you.
