Your thread title is inaccurate. Your money was not 'stolen'. You didn't use 2FA which helps to prevent unauthorized access. Someone gained unauthorized access to your account and made unauthorized trades. This can at least be partially attributed to your refusal to use 2FA, using Tor and a number of other factors that are completely outside of your exchange's control.
If btc-e actually cooperated and provided any information of other customers in this situation (without a police/court order) it would set an alarming precedent and I am sure they would lose many customers over it.
Wouldn't his BTC/Cash still be considered stolen? I mean if someone breaks into your house while your away and you only locked the one door lock, would it make it any less of a break in or explained as a 'unauthorized entry' because the home owner had a dead bolt and/or alarm system that he didn't use? Sure he had extra precautions he didn't utilized that may have prevented the break in, but it doesn't lessen the fact that someone still broken in to his house all the same, no?
As to the OP, you should defiantly enable 2FA if you haven't yet. Say your house gets broken into, you are basically using the argument "I didn't bother to lock my door because thieves could have just picked the lock anyway". Hopefully that puts it into a better perspective.
Very sorry for that loss though, I do hope you get some form of resolution from it
