If you believe this Ryan guy, credit cards stored on the same server as the key to decrypt them, Lish passwords stored in plain text, they've known for some time and lied about what actually happened and now they're saying "we won't do anything about it" via email?
"You are of course free to take any steps you deem prudent or necessary to ensure the integrity of your online presence."
Unbelievable.
Edit: not to mention they "made a deal" with the hacker not to tell anyone? What the hell?
