Perhaps you missed these two as well..
That's cool man, but it doesn't seem that Wade has been banned, just the thread (s)he started deleted.
From what I recall it was just asking people's view on marketing aimed at Christians. As others have mentioned, it's just another niche. (Though maybe one that can be exploited in unique ways....)
I can understand the trolls and ebook whores getting booted and pointless or self-promoting threads being closed but this one didn't seem to fit that pattern.
(EDIT: Thinking about it Wade might've referred to his/her site - can't remember if that was in the post or sig though.)
