> Have you considered simply not using a username that ties back to your real identity?
I assumed it's been Internet 101 for several years now. To the point I don't remember when I used my real name on the Internet. And whenever I do, it must be a really important and a well thought-out reason.
Moreover, I use a different nickname for every service so that if someone looks up dvfjsdhgfv they will only find HN and HN-related posts.
