The admins are well awared of this situation. It had been addressed (although not quite successfully) and will be addressed again very soon (which hopefully will produce more of a result).
Here, I would like to ask all players to be considerate of your fellow players and try to restructure your routes. No more than 1 0.5 frequency is expected for each route. Please restructure your routes when deemed appropriate.
At the same time, please stop accusing other players in the open. As StephenM has said in various occasion, we don't want this forum to trun into that of another airline sim. As a result, this topic is locked.
