To say 4chan isn't a cesspit of racism, mysogony, anti-semitism and disgusting content would be a lie. But the same is true for twitter and people buy their blue checkmarks there all the time.
Not sure on this one, Reddit is arguably the worst place on the internet and has a lot of oversight, is heavily curated. Part of the reason it is so bad in fact. The pendulum just swings the other way compared to X and 4chan.
