Who are you to dictate who can and cannot trade? Who died and made you king of bitcoin?
Bitcoinica is not an exchange. We guarantee liquidity based on current orders in the market. If you build a fake bid wall, Bitcoinica will think it's easy to sell.
If you sell on Bitcoinica in large amounts, it's likely that the system will give you a good price since it's easy to sell. However, if you now suddenly cancel all the orders, the system will fall into a trap and make a loss.
We have already pushed some updates to refine the algorithm to prevent cheating like this. But the financial loss is not just affecting the platform itself, but other traders as well.
I don't decide who can or cannot trade. But for any transactions on Bitcoinica, I'm the counter party. I can refuse to offer prices which definitely don't reflect market conditions.
For 99.9% of Bitcoinica traders, blocking malicious accounts will benefit you.
According to our statistics, you have withdrawn $142 net. We have no intention to disclose your personal information, but it seems that you didn't count the numbers accurately.
I don't like you keep speaking of "malicious" accounts. Not at all. No account is "malicious". No one is hacking your site or stealing other users' passwords. Everyone trades at your website by filling in buying or selling orders. You should work hard on improving your website instead of criticizing your users. I have lost lots of money due to the crap algorithms.
