This is nothing new. This was one of the reasons I never even joined Twatter.

I'd really love to see what the twitter (or YouTube) feed is for a normal user. I don't doubt that the algorithms push extreme content, because that's what humans are naturally drawn to. After all, we want to look at car crashes aswell. However, I'm just really curious on why these people simply don't train the algorithm better.

Every now and then I get some right-wing(ish) video recommendation on YouTube and after I mark it as "not interested" it dissapears and it just goes back to recommending me stuff I'm actually interested in. Same with 1 minute long videos. I don't need to flag too many of them before it realizes it's not the content I don't like but the short lenght. In my personal experience twitter is way less agressive at pushing such content but even when it does the same solution works there too. "Not interested" and it stops showing up. Except for cat videos. Those never stop showing up no matter how often I mark it.
