clearly these are people who own a computer and some money and don't have much more to do with their time than click buy or sell on gox.
it's not like they can take their money out of there anyways... this is why bitcoin will forever be unstable

...everyone gets stuck in gox forever in an endless loop of buy and sell until gox shaves their fiat and coins down to infintesimal sizes that can't be traded or withdrawn, then keeps those too
