The reason why is some posts were deleted. This is beyond permaban. Permaban hides the posts but don't break the threads. You can still get to the permabanned members posts through their post history.
deleted posts can't be found in the threads, or through any other means (including their post history)
Since posts aren't deleted often (and really should never be) #1 will probably never be fixed.
As for the game priority, it was never intended as the final system and was put in place to make some people happy. I'm hoping we can rework the game collection so you can more easily sort your favorite games and display them on your profile.
