Slander/Promotion of violence is illegal.
Shock content (like porn) should be tagged as such and censored for those who opt in for it, especially if the platform has children on it.
I think social media sites have the right (and responsibility) to remove bigoted content
Sharing personal information should be illegal
No offense but I can tell you don't have fictitious news stories cited when people shout slurs in your face IRL. That would probably change your mind on how social media companies should operate.
Also how is this a 'nanny state', its a social media platform, not a government. Outside of some basic "it should be illegal to commit terrorism" statements, I haven't really talked about legal issues here.
At the end of the day, Telegrams CEO was arrested because he didn't do squat over user safety. Fully deserved IMO.
