Hummmm, "Elon Tusk", the newest member of Twitter?I wouldn't expect Twitter to have any such. Why would it? That's a problem external to Twitter.
Seems pretty easy to set up, to me. Elon sends whatever he wants to go to twitter either by text to thepoor sapsfearless employees appointed as his censors, or more likely into some sort of e-mail queue where it will stay until one of the people appointed to monitor his tweets checks it out and either sends it on to the twitter account, or deems it unworthy and deletes it. Of course, Elon would have to give them access to his twitter account, but that's trivial... at least, trivial for setting it up, but perhaps not so trivial for Elon being willing to put others in control!
