responding here to slimvirgin's point about purging of the archives that stops people gaining accessed to wmf held archives of the list but it does nothing about personal copies of mailing list correspondence kept by individual arbitrators there are some arbitrators who have been on the committee for years much longer than i was and if archives are purged then any personal archives they may hold would be the next logical target there are ways to make that attack vector less vulnerable though and purging the archives would ensure that new arbitrators only have access to what they get while on the committee so on balance i think purging of the archives is something that should and likely will be done trouble is it looks like it is a bit late now and it also raises the problem of verifying the leaks how can you verify that a leak is genuine if the mastercopy has been destroyed
