Let's not turn mountains into molehills here, Twitter isn't really closed, it's just authwalled. So, burner email is all you need to read all the tweets, errr, X's?, that you want.

And if Twitter doesn't like you, why is your ability to communicate with an official regulated by this private company? And Nitter is likely to get shutdown by Twitter any moment now in the same way as Apple is trying to shutdown Beeper.
