The sourcemod.cfg has stuff regarding that
Code:
// Specifies how admin activity should be relayed to users. Add up the values
// below to get the functionality you want.
// 1: Show admin activity to non-admins anonymously.
// 2: If 1 is specified, admin names will be shown.
// 4: Show admin activity to admins anonymously.
// 8: If 4 is specified, admin names will be shown.
// 16: Always show admin names to root users.
// --
// Default: 13 (1+4+8)
sm_show_activity 16
I think using 16 will only show stuff to the root users "z" flag maybe
