I'm using tiktok for a while now and just like 10% of what I see is really just fun things, memes, or really interesting people talking. But the algorithm learned that I like raging, controversial and kinda pessimistic videos. Yes, I do enjoy those - that's how our brain works - but only for a limited time.
Instead the algorithm never stops to feed you that content, and you end to get caught into a downward spiral of the same bad content that unconsciously keeps you engaged but ruins your liver at the same time. Luckily I'm able to notice when it's harming me and shut it down. Too bad I have to use it for my music career, so I can't erase it for now...
Good for you that you managed to get rid of it
