They suggest they where not hiding it and to be honest. I think what really happen is they found someone on their network, shut down PSN and then got someone to do research. Should they have told everyone they MIGHT have had their information stolen?
Yes.
Did they? Well, no. That would look bad, hacking looks bad. The issue here is we rely on them heavily. I suggest not giving control of your credit card information to any online shop. Use pre-paid cards and only use your CC if you can personally swipe it.
This goes for Xbox too. They can secure it all they want, all systems are breakable. Plus, I had a really bad experience with taking my CC info (when I used it a long ass time ago) off my gamertag. I basically called in, they said it was off and a year later I check when buying a game and its there... :?
