Egamma, I would never publicly accuse someone of multi-cheating unless I had rock-solid proof (such as a message that was clearly meant to come from another character than the one it was sent by, for example). I will take it to the Titans as you suggest though.
However, as an aside, in the argument earlier it was brought up what harm these characters could possibly do, sitting as they were in the capital doing nothing of note. Well, they can vote in elections.
