Personally Identifiable

Andy Baio did an experiment with Mechanical Turk which is somewhat interesting on it’s own, but what really caught my eye was:

Upload a photo of yourself…

DON’T provide any identifiable information, like your name or email, since that’s a violation of MTurk policy.

When did technology take over so much that our face, the single most important aspect our brains use in identifying people, become not personally identifiable information?
