Well, too late

And that's the thing with privacy, once it's gone, you can't get it back.
When I started with Bitcoin, I used a random generator to create a username. But I never expected to use it this long, and by now I've used it on other sites too. I can't take that back without giving up everything I've done in the past 8 years, and being a Newbie again. So having a reputation doesn't go with having privacy.
