A faux pas, but I’d say it’s still public data. My thoughts are: We can have legitimate reasons to want to do a quick background check on someone, but we can’t control what results pop up. And when we chose to let our data be public, that’s exactly what happens - it appears in search results.

What we can do is not click on the links that will tell us more than we ought to know. (Assuming the title alone doesn’t do it.) We can also choose not put our entire lives on the internet, though… Interesting story!
