Well, you need to take your own advice. You see, I have googled, and thus found out that TMOUT will only log users out with open terminals. If you're logged into the desktop and the terminal is not open, you'll stay logged in with or without TMOUT.
Maybe next time before you go off on someone, you make sure you know what you're talking about.
