Because, children, people who invest more than they can afford to lose may be driven to track down the kind of people who tricked them into handing over such a large some of money and seek to 'resolve' the situation personally. Take away everything a man has and he's nothing left to lose. They know this.
What's the problem with it? I gained (not much, 0.4 btc) from scrypt.cc, which means, luckly for me, I "stolen" some money to other members.
I'm happy, and I don't fucking care if someone who lost money can't pay the rent anymore, because it's their fault, and they deserved it. If I had lost my money I would be happy anyway.
I think Marcelo is coming back with a new scrypt.cc built from scratch, with zero balances (hacker stolen all money

). So it's time to restart the game and see who's going to gain more money.
Good luck
