Re: mtgox.com has blocked my account with 45 000 USD in it!

...
7. I meet man in IRC who offer me to make deal, he send me ~9000$ BTC I send him ~3000$ liberty reserve (simple trade) minus some fees, I accepted, trade was made. btc rate in that day was ~0.30/BTC.
8. After month after trade was made (with man from IRC) I noticed that my mtgox.com acount is blocked.
9. Mtgox.com starting asking from where I get those 9000$ BTC, I explained.

After the deal with the stranger, have you done any BTC deposits to your mtgox account?

No.

How exactly did mtgox refer to the 9000$ BTC in question, in their inquiry?

He blocked my mtgox.com account, and started asking from where i received 9000$ , I explained him.

Baron, one source of confusion for me (and maybe for others) is confusion about when you are talking about BTC, and when you are talking about LRD, and when you are talking about USD. Could you try to remember to specify which you mean? In this example it is clear, since you are responding directly to dkaparis, but it could get messy later down the road.
