People AFK in Unity

It is quite impossible sometimes to log into or access the unity chat to accomplish a few Record of Eminence quests, let alone even USE the unity chat as a viable option, because so many people are in it and are AFK or not using it, blocking out others that want to use it, even just to complete RoE quests.
Is there a way that SE developers can make it to boot someone out of unity chat if they don't use it for a certain amount of time, say in an hour of non-use?
This Will help alleviate the people that DO want to make use of this option in game, and help them use the Unity NPC leaders more easily.

I do remember reading some time back they had planned to increase the amount of people that can access Unity at a time; has that ever come about?

Firmly believe that anyone in any zone for more than 1 hour should be dropped from unity chat. or.... we could just remove people from unity chat alltogether and just make serverwide dragon announcements(that you can opt out of). changing the ROE to something less irritating.
