Edited the plugin here slightly...

Changed up this console variable:
Code:
// Action to take on VAC banned clients (0 = ban, 1 = kick, 2 = admin message)
// -
// Default: "0"
// Minimum: "0.000000"
// Maximum: "2.000000"
sm_vacbans_action "0"
It should tell all admins in chat now when a VAC banned player joins the server and connects if that console variable is set to 2. The command access check would be 'sm_listvac' and by default, it's only for admins with ban privileges.
Note: Haven't compiled it.
Update: Fixed the compile, accidentally added the logging functionality inside of the switch statement without a case.
