Head Admins are not allowed to simply hand out staff ranks to non-staff members.
The only people whom have this ability are Directors (Sanchez/Trad), and even so they usually seek approval from Jackson or Chambers before setting them, and while they are set, they must be fully supervised by a Director or Head Admin, and then the rank removed once completed.
Founders are the only rank allowed to approve of Honorary In-Game Staff Ranks, Developers, Developer Assistants, and any in-game ranks not associated with the normal staff structure.
The reasoning for this is, at random points in time people were being set to SA without any approval, ontop of that, previous HAs who did this either forgot or just never removed the temp rank, allowing that person to roam free for days and even possibly have reports filed on them, as a staff member, when they are not officially staff, or on any roster.
