Just so you know I'm not unsympathetic to what you're trying to say. I certainly got bruised up a bit in the Optional Realities thread due to some poorly communicated ideas. In the end I clarified but I stuck to my prior decision there. I think that if you acknowledged that there is a personal interpretation to the position on advertising of unauthorized games that people here would at least accept that the game owners (or you) have a personal opinion which you are enforcing. Which is your right even if they don't agree with you.
That or you could do like @Miss-Demeanor suggested and provide either the direct question/answer form between a member of your staff and GRRM... or provide your authorization document if you have one. Unless you are under an NDA. It's just my helpful advice because while this thread is getting a lot of views and responses it might not be advertising your game in a beneficial way (which is your intended goal). I made the same mistake, it's an easy one to make, but continually repeating yourself is just going to crush your soul and feed spurring people in the community to question the position because nothing was answered it was only repeated. (same mistake I made in the OR ad thread)
