Here is the question you all have to ask yourself:
What are you getting out of it when you disrupt another's gameplay?
I wouldn't get anything out of possibly making someone (and usually a new player) close out their game when they maybe had their very first kill or maybe even 5 kills that they can't land now, because they're staring at their desktop.
I mean if this sorta thing makes you laugh then each to his own, just giving my own opinion on what I would and wouldn't find funny.
If I was a new player, and I had my very first aerial kill and then someone told me to press ALT F4 to lower my gear so I could land my kills, I sure as hell would not be laughing.
But hey, some people get their kicks out of that.
To me, it's just a childish, high schoolish prank that is very immature.
It'd be the same as pulling the power cord on your friend's Nintendo after they had already gotten through 40 levels of Ghouls 'n Goblins (a game which had no save option btw).
Oh and btw, I know it's just a game, but game or not you're providing your own entertainment and amusement off of someone else's misfortune and possible frustration.
My 2 cents.
Guess I'll get off my soapbox now.
