Back in college in Washington, I had a presentation to give in a class about privacy. To illustrate how very little of it we really have, I essentially doxxed the professor in front of everyone (of course, with his permission-- he had final say on what was actually shown to the class in the presentation) and demonstrated how public most people have their social media settings set to and what information was actually in the public record. Apart from things like public Facebook photos and things like public mortgage records and salary info for public school professors, I used the fact the DL number was deterministic to make a really good (and apparently correct) guess as to what the number really was. The professor was a really good sport about it.
