Miernik,
I think we are both saying the same thing: MtGox did not lock the account - Dwolla did.
When the situation came to light, Mark Karpeles brought the hammer down hard and XZ's withdrawals from MtGox were recalled. MtGox reported the issue to Dwolla, and Dwolla shutdown XZ's account.
My point is that MtGox support guys may not be aware of what Mark said on the forum, because they stopped replying to XZ. It took months of collective effort including PM to Mark to obtain a written clarification about the ownership of money from both MtGox and Dwolla.
Xiong,
Our lawyer is exploring options of what to do with the money. Most likely we will end up turning it over to a GA state or Fulton county agency and you can follow the due to process to claim it from them. I will send you an email when we complete this hand-off.
Thank you,
Keyur
