Try editing the defines like this and compile the plugin. Kind of hacky just changing the define to get the player kicked. If he's still on the server that is.
Code:
//Command used to delayed ban.
//Default is "banid 0 %s kick"
#define BAN_CMD "sm_addban 0 %s macrodox; sm_kick %s", reader
//if banid is used, write to banned_user.cfg manually.
//#define BAN_WRITE
I'll probably add direct SourceBans support if i see servers running both the plugins.
