Yeah, that’s what the little shield next to his name means. And if you look at his account, he’s in the “moderators” group. I’ve mostly seen him in action in the Game Room forum. (He’s one of the mods there, along with Chronos and raventhief.)
Check out the link for the list of mods, he’s there:

ETA: He is also a moderator for Comments on Cecil’s Columns forum (see here).
