I want to vote for two:
Points are funhouse batshit crazy: Can be given and taken away at whim by mods who do so for their pleasure and their pleasure alone
Points should be part of a forum game with complicated rules
The game should be the whim of the mods.

There should be crazy-ass complicated rules in place that rarely make sense or apply to anything, sometimes contradict one other and change on a regular basis - at the whim of the mods.
But - the rules have to be stated before a point can be given or taken away. Don't get me wrong - say Pale posts a picture of Pikachu and you want to take a point away from him. You could then go into the Point Rules thread, add a rule that says posting pictures of Pikachu will cost you a point, then take the point away from Pale. All rules just have to be documented. The Rules thread could also be a place to report violators, although reporting a violator will cost you a point as well.

Oh, and no removing rules once they're in place. You can make a rule that voids a rule, but the original rule must stay on the rulebooks.
