I worry about this. As a teenager I was thrilled to death to have my name on the internet. I knew it was me, because I'm the only person with my full name in the entire world--no joke.
Then I got into a profession that considers this sort of writing to be, if not a complete crime against humanity, definitely not a bonus for the career. I just hope nobody googles me until my professional activities outweigh my fanfiction. I removed my name from several prominent places (like the Archive). No one can actually access my stories anymore, but it's still coming up when other fanfic writers referred to me in their stories OR in sites that are no longer maintained but still exist. Still working on that.
On the plus side, I recently discovered that I have a second cousin who shares my same first and last name (with a different middle name). I am now planning to blame every citation of me that I'm not thrilled about on her. I feel it's somewhat evil, but she's a horse trainer so I doubt the horses care if she wrote fanfic in the past!
This puts a whole new spin on the idea of anxiety of authorship.
