Freedom of speech should only have its borders within the laws. So as long as someone is identifiable on Twitter, I think Twitter should not censor him, because he can still be taken to court.
The Trump case shows the problem. Banning him did not just silence one person (at least on Twitter), but it also affected his more than 70 million followers who could not longer see his tweets. So it is not one censorship, but 70 million censorships at the same time. It is like banning female nipples. That is not just a problem for the nipples, but much more for the people who would love to see nipples on Facebook and Instagram, but can't because of some community guidelines that treat people like kids, who could somehow be harmed by seeing nipples.
The Alex Jones case showed that you can successfully sue somebody in front of a regular court for his tweets, posts and videos. Courts are the place where things like those should be settled. Let him posts what he wants and then sue him later! Censorship is only needed if somebody does something obviously illegal like posting nude photos of someone else that could not be repaired.
