My brother still doesn't have his stuff back btw. And by stuff I mean all his (6k) gold, 3 of his characters, and various enchanting mats, gems, etc. Just thought I'd update the "keylogging is only a slight and momentary inconvenience crowd".
That's really odd. I wonder what the difference between your brothers experience and mine was, did he not long on for a while? I logged off one night fine and logged on the next midday with stuff missing, and opened a ticket right away, parhaps mine being so much quicker was because there was less time for the hackers to move the gold around and left an easier trail for blizzard to stop.
That said, I got most of my items back right away (within one hour) so I don't think even that was a factor for those items either, just for the herbs, gold and stuff.
Really wierd that there would be such a different response for your brother and me, I wonder why.
