A plugin won't necessarily respect sm_show_activity, but the base SM plugins do.

Looking at the code in the linked plugin, I checked its sm_godmode command. It does not print anything publicly whether using the chat/console command or the menu.

If you're using sm_slay from the base plugins and it's printing like "<name>: Slayed <other name>", then check that value of sm_show_activity is actually set. Using the server console you can just type "sm_show_activity" or from your client console do "rcon sm_show_activity" (or sm_rcon or whatever).

If the value is 12 and someone can see that message, then either they have the generic admin flag set (you can check with sm_who while they're connected) or you have some other plugin doing something unwanted.
