Camping is indeed part of the game, hell, it's part of life!
A real soldier would camp.. He would keep his head down at all times and not run around like a madman!
Of course, this is just a game and its a fair point. In a game, nobody likes being camped.
However, there is no reason to exclude the map. Instead, I would stipulate in your Blast that you do not wish to play BOG and if it comes up on the Randomizer then you expect to play another map.
You should realise that this might lessen your chances of playing matches, of course.
