As for the accusations, as an outside-group on this matter I believe that the GMs have no part in this, they are too much part of the game and represent the freedom of this game to try and manipulate it for themselves. The Titans are another matter, they may have something more to do for their characters versus the game. Then again I don't know who they are, but it's still a possibility that there's a rotten Titan in the mix.
