This troll used an admin name with one more letter. How do we deal with admin identity theft? Should instance admins reserve usernames preemptively? This troll will likely try u/Desssalines or something similar next. Maybe mod/admin flairs should be more flashy to avoid such confusions?
I'm thinking maybe a new feature where instances can switch off custom display names for new users, or wait X days/X threshold until new users' custom display names are made public?
