The exception to this is people that change their usernames into similar versions or simplified versions of their current username. It's like how Frosty got rid of the numbers next to her name or ZombieNinjaPirate switched to ZNP-TBA. I can still tell who they are! And the new username sometimes has a better ring to it. It's like if you changed yours to just say "fetus" or something because everyone calls you that.
