Signal’s smartass ad exposes Facebook’s creepy data collection
Facebook is notorious for generating creepily personal ads from reams of user data, but most people don’t understand how the system works.
Now, an attack ad campaign by Signal has shone some light on the opaque surveillance dragnet. The privacy-focused messaging app tried to buy “multi-variant targeted” ads on Instagram to show what parent company Facebook knows about its users.
The resulting adverts can be eerily intimate and potentially harmful. Just last week, researchers found that Facebook had allowed advertisers to target teenage children interested in smoking, gambling, and extreme weight loss.
