I quite doubt that. If they have indeed taken over control of their servers and everything, we at least would see a statement on the front page stating that it has been taken down by x agency -- that's how things go usually. I seriously think that the co starter/partner of btc-e is still in full control of everything. But then again, what value does it have when the exchange might never pop up allowing people to cash out? Zero. Not that I believe much will change, but there is not much to do other than to wait what will happen in the coming 5-10 days as btc-e stated.
Well, we can now see the takedown/seizure message on btc-e.com. Maybe hasn't propagated yet to btc-e.nz, etc. or maybe they only seized the .com. I don't think Vinnik is anybody -- an early whale/investor or low level admin at most. Definitely not an owner according to insiders. But it doesn't matter. Shutting down the site (even if they couldn't seize any funds) means that it isn't worth it for the owners/admins to pay the fine and try to continue operation. They will be in too much danger. I wish there was a way that users could be repaid but, there just isn't any logical reason for it to happen.
