Well, what about something like 'The Libs of Tiktok', a Twitter account that routinely posts the home addresses of trans people? They get away with this by posting the address on its own, but against a trans-symbol background.
Technically, they haven't threatened anyone, but the threat of stochastic violence is legimately chilling to that 'vigorous open free speech debate' that we supposedly all want, and that is so untroubling to so many freeze-peachers speaks volumes.
You can have physical intimidation or free speech, pick any one.
I don't know too much about their correlation with Nazism though.
