I actually think the "code of conduct" culture that Rust embodies exacerbates this kind of drama. Ironically, it creates a more unsafe environment where everyone feels anxious and judged by the CoC Police. Under the CoC, I am entitled to a wonderful experience, and if I don't get it, the culture has failed in its commitment to me.
I have literally never felt "judged by the CoC police" in any project that has one. I have no idea why you would ever feel that way. Pretty much every CoC says "do not be a raging asshole". I am fully capable of not being a raging asshole, and if I slip up and am, I would be happy to be told off for it.
There have been very public instances of it happening, though the truth is people would have been just as assholish with or without one. Toxic people don't need to hide behind a CoC to be toxic, and they aren't especially likely to obey one either.
