Diablo III has already been the victim of a mass hacking spree, and I can only see this progress to a point that will be incurable once money is involved... and that the missing items and money will be used to make real money via the in game real currency auction house.
I know Blizzard is aware of this situation and failing to comment upon it purposefully, as not to lose more of their gamer's as WoW users decline. But letting people take others belongings, virtual or not, and not fully righting what was wronged is dishonest, untrustworthy, unprofessional, utterly detestable, and soon quite possibly illegal when people's money gets involved.
When money gets involved it could lead to numerous law suits which could be the very end of Blizzard as we know it.
We are people, not pixels.
Our time is invaluable.
We demand justice.
