I think the default on Sourcemod is to display the name to other admins - but general players in the game will just see "Admin kicked..."
But to check this go to [game name]/cfg/sourcemod/sourcemod.cfg
And you can see the following:
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 13
So the default is actually what I said - admins can see who did what, but non-admins can't.
