Why is Hikaru missing from the Leaderboards?

Yep, he has played a rated game in the past 90 days, or so it seems if you look at the archive of games on his account. You can see his rating changing within the past 90 days.
I've been wondering the same thing. Right now his bullet rating is 3272 and it skips him on the leaderboard, and he's nowhere to be found in the rankings at all. And this has happened many times. And more importantly, why hasn't this question even been addressed?
I noticed Hikaru is no longer showing up on the Leaderboards of Chess.com for Blitz and Bullet. That is weird.
Anyone knows why?
