Lol, "no reason to pull the "Cyprus" name out of a hat"? It convinced you, did the job, so why not?
As far as "if you are going to sue us" goes, you need to know who "us" is before you can sue, and you don't

Such wild conspiracies are simply unnecessary. They have considerable monetary operations. They work with banks. They
have to have a registered company, or no bank will work with them. Registering a shell company in Cyprus is easy, especially for a Russian businessman. There is simply no point in lying about it. There are other means to preserve their anonymity while conforming to acceptable business practices.
You sound as certain & use the same logic as the intrepid NeoBee investors did when I questioned the integrity of Mr. Danny Brewster (see pic).
If I'm being too subtle, I'll spell it out:
1. A financial institution unwilling to offer the bare rudiments of corporate information, such as address, business registration, and names of the key players likely has a reason for doing so.
2. Registering a company in Cyprus is trivial, registering an exchange is not. If BTC-e is registered as a bakery, that's not what most would consider sufficient.
2(a). If BTC-e is registered, and has not provided the registration to its clients, why?
3. Regardless, not registering a company is easier still, especially when one wishes to obscure the names of the key players.
4. Registering a shell requires a name. Even when said name belongs to some carder degenerate willing to lend it for a nominal sum. Such people are easy to flip when shit gets real.
5. Assuming that an anonymous Bitcoin financial institution will hang around when things go wrong, or when it becomes more profitable to walk with the money, is the stuff bitcointalk legends are made of.
TL;DR: This is certainly going to end well.
Re. "we aren't Russian citizens": So they're not Russian citizens & purportedly registered in Cyprus... What makes the exchange Russian again?
Oh, they
are Russians. (Could be Ukrainians, although much less likely.) Definitely native Russian speakers. They just aren't Russian citizens, or at least have stated that they aren't. The statement from them that I remember was "although we currently reside in Russia, we aren't Russian citizens" or something like that. My guess is that they have obtained a citizenship from another country and have renounced their Russian citizenship.
If the people running this thing are not Russian citizens, do not reside in Russia, and the business is [purportedly] registered in Cyprus, what makes it a Russian business again?
I'm a native Russian speaker, BTW. Haven't set foot in the place in years.
There is a reason why the prosecutor's office in Volgograd (Russia) was investigating this particular exchange and not one of the Chinese ones, don't you think so? Determining who they are and where their company is registered wouldn't be a problem for the Russian law enforcement. ...
Perhaps. How long ago was this d00d caught again, I seem to draw a blank?

And everyone knew his name, he was the golden boy of Bitcoin, he was in all the papers & shit...
