Yeah. Change my mind: if people want you dead violently, police are likely to be 15 minutes to an hour too late, and the courts a couple years late behind that. Unfortunately violence is often either solved by running away, hiding, or meeting violence with direct self defense.
Maybe after you're lucky, you can win a suit against twitter, after their massive legal team drags it out for years with N number of hurdles. You'd be lucky to sue a nobody in podunk small claims court in time to effect meaningful change for something that needed done in days to weeks.
