Deletion of the list will not reduce accusations that the ArbCom members are leaking info since they will have the same basic access as they had before. List archives even for confidential lists are often very useful objects for when related situations come up and would be useful to Arbitrators. Furthermore, deletion of lists cannot be guaranteed since arbitrators could independently archive their copies. Finally, in the very long run there may be historic interest in these lists and it would be unwise to delete them.
