Serverside entity culling may decrease the effectiveness of the wallhacks themselves, but it also makes wallhacking easier to hide. The players would only be shown through walls when the server definitely thinks you are about to see them, making it easier to play normally nearly all the time and still know where the enemy is before the enemy knows where you are. Food for thought. I have no direct opinion on any of the current hackusations or theories plaguing the forums.
