We do actively monitor the game for all such dubious activity. If anything is found, we do take immediate action.
Our request is to all players, which we keep saying again and again, 'Do not share your login details with anyone. You only expose yourself to hackers.'
Just because they advertise they can do it, that doesn't mean it's not just a scam to get your money and you get nothing in return. Having 25,000 DZ on hand does not make you a hacker. I've had over 100,000 on hand at one time and I but all of mine from Jim. You may have a case for me being crazy, but i'm no hacker.
