What happened to C9C9C9

Hi disappeared from top ranking

but there is someone with 3100 https://lichess.org/@/alireza2003

@Yousuf_Haitham , sure. But the rules does not allow you to change your username, at the maximum the from lower case to upper case or vice versa

He is 3rd in bullet and ultrabullet, so weird calling that 'disappeared'.
Was he long time number one? I'm not paying much attention to leaderboards :)

sorry bro, you're totally right.
yes he was, but still have a ranking above 3000 and isn't on the leadership board.

i thought he left lichess because of that, disappearing the leadership board, but his profile is still active.

thanks for the tip!
