I think most folks understand that Bart is just a very smart player who is delusional about his own level of importance to the game. He has the intelligence to do good in the game, but unfortunately he also has the emotional instability to do harm to the game with that very intelligence.

Most games all over the interwebs have these kinds of players, he is not some rare breed, he is just who he is. Take him at face value (even though most of his substance is clever manipulations) and just let him do his thing. He is no more or less a member of the community just because of his approach to the game.
