Lacking anonymity forces the Titans to ensure they are being as neutral as possible and makes the whole process feel more open and friendly.
I'm not so sure about that. Feel more open? Yes. More friendly? Meh....
More neutral? I don't think so. In fact, I would think that it would, in fact, cause more accusations of personal favoritism and realm favoritism. If it was known, for example, that there was a Titan that played in Keplerstan, then any decision that took action against Evilstani, or any character/player in Evilstani, then any such decision could be viewed as biased based on the fact that "The Titans play in Keplerstan". This would be even more likely if there were a few players in Evilstani trying to play fast and loose with the rules.
And even if it wasn't true, observational bias would play hell with anything like that. Players would see what they want to see. And they would be vocal in their assertions. And people who hear stuff like that believe what they choose to believe, rather than put in the time to do the research. That's the very foundation of most political systems: "Barrage them with bull!@#$, and eventually they'll start to believe you."
A pseudonymous system would be much better.
