Is this a bug or something intentional?

My question / gripe is not about the game itself, but every time I log in, I'm asked whether I want to either "allow" or "don't allow" my game information to be posted on Facebook. Can my choice of "Don't Allow" please be made permanent? Or can this choice be left to be made in a player options menu?
Don't get me wrong, I think that Facebook connectivity makes for great advertisement, but asking me to share my game activity every time I log in is quite annoying.
