Can someone tell me why people feel the need to post on the forums that they are leaving the game? Turbine KNOWS whether or not you have an active subscription. You can say good bye to your friends in game and/or on your guild website.
The only reasons I can think of is that people are trying to garner sympathy, draw attention to themselves, punish turbine somehow, or just to stir up some trouble one last time.
well....stop it.
If you are leaving the game because you are dissatisfied with some aspect of development, server population or something else that is affected by the number of active subscriptions and resulting revenue, driving away other potential ploayers with your whining is just making matters worse for the friends you are leaving behind.
So....my suggestion (finally) is to make the user populated portion of the forums unavailable to non-subscribers.
