2600 Magazine says they didn't. They posted names and email addresses of DOGE employees.
My partner works for the government in a mid level management position. I'd be pissed if someone on X posted her name and email address in an article that borderline encouraged people to email her in a not so positive manner.
It seems that X deems names and email addresses to be personal info. I'm pretty sure this was in Twitters ToS pre-Musk as well.
Why does breaking X's ToS not warrant an account suspension? You can even sneeze loudly in some subreddits without falling afoul of inciting violence.
Perhaps this is a shift away from cancel culture? I don't see why that's a bad thing.
