After posting the thread, I found this.

New Rule
Double logging has recently been allowed. The characters cannot be used to power level or power rank. In the event of a full server, double logged players should remove one character.
If you are active on one character, the secondary character is considered AFK and will be treated as such. You double log at your own risk.
The Lag Limit
The server appears to lag a lot once the player count hits 19+. In response to this, if the server has 18 players or more, players are asked to remove one of their two characters to make room for more players.
PKs/Admins, please ask for volunteers to drop. If none are found, to promote fairness, all double logged characters should be asked to leave.
Now it does not specifically SAY you cant have more then 2 characters But this is what I remembered seeing that I felt implied it.
