Yes: other people being frightening-as-fuck PII loose is totally familiar. :-)
I'm almost certainly much older, and thus have innumerable USENET posts signed with a "sig" I used back then containing full name (yes.. even the middle initial..). The content was sufficiently weird that I suspect most wouldn't know what to make of it, and yet of course there are people able to make quite a bit of quite a little. "Journalists", for example.... <coughs>
But that was long ago. I guess I've been mostly anonymous since, and completely fine with it. In fact, I find funly joy in seemingly becoming a personage roughly defined by a "handle" and the momentum of the accumulation of its verbiage offerings.
