I feel like most accounts do that. They submit 1 run to their profile and never come back online. I think that you should be able to change your username to that account even if they have only 1 or 2 runs. But for now, I would ask @starsmiley or @meta if you can change it.

Any chance to request for a username if player has been inactive in the future?
