Here is a perfect example of what happens when data you prefer to keep private ends up in the wrong hands. Or worse, when data about another person becomes public, and can then be used to infer information about you based on a past or present, direct or even indirect relationship with that person. In this case, there isn’t even proof, but rumor is more than enough if the spotlight is bright.
