In anonymous systems, where we don't use real names, your "handle" has an "age". That becomes your most prized possession.

I have a reddit account thats over 12 years old. I have left the posts/comments open. That means, my "post history" becomes a way to advertise my skills. I can reference comments from a year ago or 6 months ago about a certain topic to show how I handled something. That does have an effect on people.

As opposed to a random 1 day old account. No one takes them seriously, I guess the same is here as well
