Some highlights of what we did and some stuff that I haven’t seen reported before: 🔴 The incomparable @rob_barry + @JohnWest designed a system with dozens of automated TikTok accounts. We gave these 🤖s hidden interests. That is, they rewatched videos with certain #s + images. https://t.co/tbMQvgT7MQ — PolitiTweet.org

How does TikTok figure you out so well? How does it know that thing you never told anyone? An insanely powerful algorithm. We created dozens of automated TikTok accounts that watched thousands of videos to learn more. Our @WSJ visual investigation: https://t.co/Niva4NT7LO — PolitiTweet.org

🔴 From this we learned, you only need to watch videos for the app to figure you out. You don’t have to give it any other info for it to get at your unspoken desires. You don’t need to like, follow, search. It doesn’t need to track you across the web. It just needs you to watch. — PolitiTweet.org
