How do you know this?
Logic would indicate that Alex is a moderator.
Click on Narses’ screen name in any reply by him or her. That will magically transport you to his or her FR profile page. If it’s still up then he or she has not been banned, you’d have gotten a message staing that instead of a profile page if being banned was indeed the case. The mods just couldn’t keep it secret any longer I guess, lol.
