Sucks since I just got done replacing two cards from the playstation network fiasco lol
Yep I still have my old Sony account from when I used to play Everquest and EQ2. I didn't have to worry about it since that card is long gone.
One thing that can happen is the sites we purchase from don't always keep up to date on their site security software updates. Hackers love that because when an update comes out it tells what it fixed from the previous version. It's like handing a hacker a walk thru.
