I did a little experiment a while ago, I've watched only videos of girls using their body to promote their videos. I went into their accounts and watched and liked everything where body parts were a huge deal in the video. It took me an hour to have my for you page filled with girls showing off. I let the algorithm go like this for a week and then i changed tactics. Every video starting with a woman, i would swipe away. I didn't even knew what the video was about. I combined it with looking up videos about food, plants and life hacks. After an hour the girls were long gone. For a whole month the algorithm kept showing me only what i was after. Once in every 10 to 15 videos there was an ad or something super viral. Thats it.

You control the algorithm. It shows you what you want to watch not the other way around.

I also took a tcpdump while the app is closed. Oh boy.
