Admin Usernames to Reserve

A message from @admin carries weight. Users assume administrative authority. When attackers register admin-style usernames, they gain instant credibility for social engineering attacks. Here is every admin variation you need to block.

Core admin terms are obvious but frequently missed in variations. admin, administrator, and sysadmin are blocked on most platforms. But admin1, admin2, xadmin, admin_official, and the_admin often slip through. Use pattern matching to catch any username containing "admin" as a substring.

Moderator and staff terms carry similar weight. mod, moderator, moderation, staff, team, crew, and employee suggest insider status. On community platforms like Discord and Reddit, moderator impersonation is a primary attack vector.

Official and verified terms imply platform endorsement. official, verified, real, authentic, and legit make accounts look sanctioned. Combined with a brand name (@nike_official), these create convincing impersonation.

Platform-specific admin terms depend on your product. If your app has "Hosts," reserve host and hosting. If you have "Creators," reserve creator and creator_support. Match your admin terminology to your product vocabulary.

  • Moderator terms: mod, moderator, staff, team, crew, employee
