Tribute

Tribute is a system where you can donate certain items to a tribute NPC and gain points which may be used to convey bonuses to your character. Toggling tribute on spends tribute points every 10 minutes. There is both individual and guild tribute. In addition, tribute points can be spent to activate some trophies.

The maximum amount of tribute you can bank (Current Favor) is 800,000. For guilds (Guild Points), it is 2,000,000.

Tribute Logout Auto-Off
With the September 17, 2014 patch, you may toggle an option to automatically turn off [spending] tribute when you are not logged in.

From quick testing it appears that if you enable Tribute Logout Auto-Off, in addition to turning it off if you camp out, it will also turn off your tribute if you go link dead or quit the game.
