It is not the first time I read about a balance being withdrawn a few minutes after making a big deposit. How can a 'hacker' know that someone is going to make a big deposit, log into his account and withdraw the balance right after the deposit? If that happens once it might be a coincidence but this has happened multiple times. Maybe someone has active to the staff part where they can see the deposits. Primedice let's strangers into their test enviroment so maybe one of them has planted a backdoor somewhere.
