为了奖金存款，但是账户立刻被冻结了

我在这个交易商那开了一个真实账户，并通过WebMoney向我的账户注资2000美元，然后我收到了600美元的奖金。仅仅过了12个小时，我就发现我的账户被冻结了，并收到一封电子邮件，说我的账户因为套利而被关闭！但我根本没有在我的账户上进行任何交易，最重要的一点是，在这种情况下交易商封锁了我的全部余额，他们不允许我提取我的初次存款（2000美元）。他们向我提到客户协议的第5.2节，声称他们有权冻结我的账户，冻结我的所有余额，甚至冻结我的初次存款！我真的不明白这是怎么回事......我什至没有在我的账户上进行任何交易。这显然是一个骗局！！！

Deposited for the bonus, but account was blocked immediately

I opened a live account with this broker and funded my account via WebMoney with an amount of $2,000, and then I received a $600 bonus. After only 12 hours, I found out that my account had been blocked and received an email claiming that my account had been closed because of Arbitrage! But I did not open any trade on my account at all. The most important note, in this case, is that the Broker blocked my whole balance and they did not allow me to withdraw my initial deposit ($2,000). They referred me to section 5.2 of the client agreement and claimed that they had the right to block my account, ALL of my balance, and even my INITIAL DEPOSIT! I really can not understand what is going on here...I even did not open any trade on my account. This clearly is a SCAM!!!
