Musk previously initiated a discussion on optimizing the X commenting algorithm in the community, and CZ replied with four suggestions: 1. Prohibit robots from automatically replying, or allow authors to restrict replies and prohibit the use of robots; 2. Support sorting comments by the number of account followers, account registration time, etc. (priority is given to displaying account replies that have been followed for a long time); 3. Support sorting comments by "people I follow"; 4. Remember the last ranking preference.
