Yep. That article says that if everyone agreed to distribute the ashes a certain way (aka. rolling), then the Master Looter must abide that agreement or its a "scam" which is against the TOA. The Master Looter can be suspended and the ashes taken away from the winner. Unfortunately, the article also says that in some cases the loot will be left "unassigned" meaning no one gets it.
Lame-o.
