Two weeks ago we discussed news that some indie developers had found a way to manipulate ratings for their games on Xbox Live. Now, Microsoft has amended the rating rules so that only Xbox Live Gold members can rate such games through the service's website. "By implementing this change, we believe our customers will experience more consistent ratings and a significantly reduced potential for abuse across the entire Xbox catalog. We have also investigated rolling back suspect votes, however, we determined it will not be possible to do this. In addition, we are investigating users who may have violated their user agreement during this series of events."
