Maybe try to block the command "/spec" ?
PHP Code:
/* Plugin generated by AMXX-Studio */
#include <amxmodx>
#define PLUGIN "New Plug-In"
#define VERSION "1.0"
#define AUTHOR "User"
public plugin_init() {
register_plugin(PLUGIN, VERSION, AUTHOR)
register_clcmd("say /spec", "block")
}
public block()
return 1;
