I agree on the points expiring after, let's say a year without any infractions. I've had (still have as they don't expire currently) points against me but I've tried my best to not break the rules anymore and I think a good faith effort to straighten up on the part of a poster with infractions should be taken into consideration. After all, if a poster gets points, then cleans up their act...the points did their job and I think it makes sense to reset the poster's points.
