I don't think it's deliberate, I see it as them being incompetent. There's no reason that Blizzard would profit from having legitimate players lose equipment to random hackers. That just drives customers of the Auction House away. There's also no incentive to have an auction house that doesn't work 50% of the time. They just suck at their job.
It's not going to help being upset anyway. But in any case, I don't expect a ticket response for at least a day. At least the prices on the market will go down and affordable gear will be available.
