Worse than alt-tab was the WB feature that let you use ctrl-alt-del which completely halted all network activity without dumping your connect. The WB host uses a 60 second timeout, so you just start counting when you hit ctrl-alt-del and then hit ESC before 60 seconds. On everyone elses FE, you just poofed out for up to 60 seconds, reappearing around where you disappeared.
I don't know if they ever disabled that one, but it sure as hell was commonly used a while ago, almost as bad as the wussies in AH now who alt-f4 and poof out as soon as they're at a disadvantage. IMHO the FE should detect if the alt key was pressed at the time of the disco. If it was, there should be a severe point penalty the next time they log back in, since the only reason to do that is to prevent the points loss and deny someone else a kill they deserve.
