I think it would be a cool update that will draw some creativity into the game that when you get hacked by someone, you get random and multiple (and I mean multiple) pop-ups designed by that person, tauting you, slowing you down, covering links, just being a big piss off to you, while you've been hacked. I can imagine the code that would allow people to design their own pop-ups would be quite difficult, and I'm sure most everyone has pop-up blocks on, and I think we would have to find a way so they don't actually get read as pop-ups.
Personally I think this would be a great addition, cause it would mean being dead means something, and hey, it would last for 5 minutes tops, and you could always heal if you wanted to.
Now go flame this idea!
