If blizzard were an actual bank there would be a run on the bank by people who have the paperwork to prove that they have money there. They would also go under and cease to function after losing all customer data like that. Then the FED’s would come knocking and heads would roll.
Blizzard at this point in time cannot be trusted to hold data. They have proven that they are incapable of starting backup up procedures, holding back ups or even restoring back ups.
Any backup gnome, yes, they are called back up gnomes, funny enough, worth their salt would have multiple back ups so not to rely on a single point of failure.
The failure on blizzard here is huge. Huge. They made a laughing stock of themselves in the IT world. How can you lose customers data like that? Frankly only idiots do that.
