From here:
Security theater
"By this time, I think every arbitrator has wiped their hard drives and reinstalled their systems (or if they haven't, they should have, Jehochman is right that even top-of-the-line security software can miss things), so even a thorough forensic inspection of everyone's computer would be pointless."
Risker is so wrong on this, it's barely believable.
What has happened is that, if the leaker is a current ARBCOM member, they have buried all evidence (and even the possibility discussion) of of whomever was the real leaker.
"Oh no, I formatted my drive as Risker reccomended! No need to look here..."
One would think, that a group whose only product/project is an online database on a set of clustered servers would have true security professionals on staff before letting community volunteers have access, apparently unrestricted, to sensitive personal data.
Look at Sony, who was lax with hard security, and the extreme beatings that were administered in the press and blogs for their failure to safeguard customer data.
Shameful wikimedia foundation, just shameful.
