Surely you could communicate with them via snail mail to reestablish your account, which I'm sure you spent quite a bit of money on.

I'm not sure how it works but they probably have your physical name, physical address of where you live, etc. when you signed up for the account. Surely they could send you a new password/username in the mail, one of those temporary password thingamajigs (you know, they're a bunch of random letters and numbers) where you log in with it and then establish a new, more easily-remembered password. That way whoever you gave your account information can't get access to it again (I'm surprised they can't do this via whatever email is linked to the account, actually...unless whoever it was that stole your account got access to your email, as well?)

If they can't go through email and don't have your real name and address to go through snail mail though, I guess you'll have to think of something else to verify you own the account, but I can't see them never giving you access to the account again. Otherwise their entire system of delivering digital copies of media comes into question--unlike with physical DVDs in which someone would have to break into your house to steal them, anybody with a decent phishing scam could make you lose potentially hundreds of dollars of software.

Frankly it would set a ridiculous precedent if they didn't have some way to restore your account to you in such a way that you were given full access to your games again and didn't have to worry about it getting hijacked (until you fall for another phishing scam, I suppose).
