I have never seen any evidence, or even any type of loose correlation, that would suggest Who Is information factors into ranking.
However, and I know many will have strong opposing opinions on this, but false, or "protected" Who Is information is not a very strong signal of quality to a human being. (the anti-spam "reasoning" is easily worked around).
