You're essentially punishing people for doing good things. That feels very wrong to me.
Next, it's not for you to decide if someone wants to have multiple personas. It's also going to vary over time.
Here's an example taken to the extreme: because you have posted publicly (at least several times on HN), is it okay for me to decide that that fits my personal definition of a public figure because you have now a reputation of being kind of a tool and then proceed to investigate and post personal details about you?
I didn't think so.
It's a perfectly sensible argument, as any person who has played both sides of the same chess game can tell you. People can and do have multiple conflicting personas, and attempting to identify [ed: coalesce] them is rarely useful. It can server to debase or solidify credentials or to explain fractures, but those are all exceptional purposes.
People have the right to put words in a different location from their money, and they have the right to invite a few friends in for a beer while the regent takes care of official matters. The press has special liberties to infringe on these rights, as they are expected to do so responsibly.
Sorry, but I find that rediculous. If Brian Warner kills someone, or James Osterburg overdoses that is not appropriate for public news because they did it under their private personas? Or can Brittney Spears claim that she has two different personas that both just happen to be named "Brittney Spears"?
Frankly, as I see it, once you develop a reputation based on name in a wider community you are now a public figure regardless under which persona you'd like to hide.
