Hmm, tricky.
Firstly, MA say contact your local police... why?
Servers are in Sweden, therefore it's the local Swedish police that should be contacted as that is where the "crime" was commited?
Not only that, but we don't "own" anything, MA own everything. So surely the police would just brush it away anyway, unless massive amounts of cash were involved, such as deed to TI or cND, and even then they might not act unless it was MA (the Owners of said deed) who requested an investigation.
What should MA actually do though?
In all honesty, and I can't believe I am about to say this, but they should do NOTHING.
MA own everything, an account gets hacked and some items etc. are moved to another account..... MA STILL own everything.
Until MA grant us the right to actually "own" items, they aren't going to do shit because legally the only crime that was committed was the hack of your account/computer, and unfortunately MA have their asses nicely covered by placing the security of your own computer in your own hands (which is the way it should be). Of course, proving that it was MA's own database that was hacked and not your PC is virtually impossible, and MA would never admit to being hacked as it would be committing financial suicide.
So basically, if you don't own a Gold Card, you're screwed if you get hacked.
If you do own a Gold Card, then the blame is 100% at MA's door, but convincing them that their security system has been compromised for both encrypted user account data and Gold Card number generation is a tall order, so we're still screwed. On the plus side, owning said Gold Card does make your account 100's of times safer against getting hacked, if not more!
That's just the way I see it at the moment.
