blank - noun - Someone who has scrubbed or never created any substantial presence on the Internet. No social media accounts (or deleted ones), no domains registered, no known e-mail addresses, no photographs, no projects of any kind. While an impressive privacy-related feat in the twenty-first century, it is not without its drawbacks.

e.g., "I'm sorry, but we can't hire you, because we can't complete the background check. As far as we know you don't have any kind of background. You're a blank."
