Indeed. Having said that, I think arbcom must take great care to afford all involved in a case an opportunity to give evidence in their defense. Towards the end of the recent Robert the Bruce case, it emerged that one innocent third party named by Robert the Bruce as a sock puppet only heard of this accusation by accident. He had not been involved in the arbitration case at all except by being named, unknown to him, by one of the parties. A sock puppet check was ordered on him without his knowledge. In cases of sock puppet accusations sometimes the accused may be able to, and certainly should always be given the opportunity to, convince the arbitrators that he is not a sock puppet. Many people use AOL which I understand uses a round-robin web proxy system, so it would be quite easy for two people with ostensible similarities in their patterns of Wiki usage to be mistaken for sock puppets.
